GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

GNU LIBRARY GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1991 Free Software Foundation, Inc.
59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the library GPL. It is
numbered 2 because it goes with version 2 of the ordinary GPL.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Library General Public License, applies to some
specially designated Free Software Foundation software, and to any
other libraries whose authors decide to use it. You can use it for
your libraries, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if
you distribute copies of the library, or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link a program with the library, you must provide
complete object files to the recipients so that they can relink them
with the library, after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
Our method of protecting your rights has two steps: (1) copyright
the library, and (2) offer you this license which gives you legal
permission to copy, distribute and/or modify the library.
Also, for each distributor's protection, we want to make certain
that everyone understands that there is no warranty for this free
library. If the library is modified by someone else and passed on, we
want its recipients to know that what they have is not the original
version, so that any problems introduced by others will not reflect on
the original authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that companies distributing free
software will individually obtain patent licenses, thus in effect
transforming the program into proprietary software. To prevent this,
we have made it clear that any patent must be licensed for everyone's
free use or not licensed at all.
Most GNU software, including some libraries, is covered by the ordinary
GNU General Public License, which was designed for utility programs. This
license, the GNU Library General Public License, applies to certain
designated libraries. This license is quite different from the ordinary
one; be sure to read it in full, and don't assume that anything in it is
the same as in the ordinary license.
The reason we have a separate public license for some libraries is that
they blur the distinction we usually make between modifying or adding to a
program and simply using it. Linking a program with a library, without
changing the library, is in some sense simply using the library, and is
analogous to running a utility program or application program. However, in
a textual and legal sense, the linked executable is a combined work, a
derivative of the original library, and the ordinary General Public License
treats it as such.
Because of this blurred distinction, using the ordinary General
Public License for libraries did not effectively promote software
sharing, because most developers did not use the libraries. We
concluded that weaker conditions might promote sharing better.
However, unrestricted linking of non-free programs would deprive the
users of those programs of all benefit from the free status of the
libraries themselves. This Library General Public License is intended to
permit developers of non-free programs to use free libraries, while
preserving your freedom as a user of such programs to change the free
libraries that are incorporated in them. (We have not seen how to achieve
this as regards changes in header files, but we have achieved it as regards
changes in the actual functions of the Library.) The hope is that this
will lead to faster development of free libraries.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, while the latter only
works together with the library.
Note that it is possible for a library to be covered by the ordinary
General Public License rather than by this special one.
GNU LIBRARY GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library which
contains a notice placed by the copyright holder or other authorized
party saying it may be distributed under the terms of this Library
General Public License (also called "this License"). Each licensee is
addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also compile or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
c) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
d) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the source code distributed need not include anything that is normally
distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Library General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Library General Public
License as published by the Free Software Foundation; either
version 2 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Library General Public License for more details.
You should have received a copy of the GNU Library General Public
License along with this library; if not, write to the Free
Software Foundation, Inc., 59 Temple Place - Suite 330, Boston,
MA 02111-1307, USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James Random Hacker.
<signature of Ty Coon>, 1 April 1990
Ty Coon, President of Vice
That's all there is to it!

This directory contains the version 2.7.2 release of the GNU C
compiler. It includes all of the support for compiling C++ and
Objective C, including a run-time library for Objective C.
The GNU C compiler is free software. See the file COPYING for copying
permission.
See the file gcc.texi (together with other files that it includes) for
installation and porting information. The file INSTALL contains a
copy of the installation information, as plain ASCII.
Installing this package will create various files in subdirectories of
/usr/local/lib, which are passes used by the compiler and a library
named libgcc.a. It will also create /usr/local/bin/gcc, which is
the user-level command to do a compilation.
See the Bugs chapter of the GCC Manual for how to report bugs
usefully. An online readable version of the manual is in the files
gcc.info*.
The files pself.c and pself1.c are not part of GCC.
They are programs that print themselves on standard output.
They were written by Dario Dariol and Giovanni Cozzi, and are
included for your hacking pleasure. Likewise pself2.c
(Who is the author of that?) and pself3.c (by Vlad Taeerov and Rashit
Fakhreyev).

The purpose of GCC pretesting is to verify that the new GCC
distribution, about to be released, works properly on your system *with
no change whatever*, when installed following the precise
recommendations that come with the distribution.
Here are some guidelines on how to do pretesting so as to make it
helpful. All of them follow from common sense together with the
nature of the purpose and the situation.
* It is absolutely vital that you mention even the smallest change or
departure from the standard sources and installation procedure.
Otherwise, you are not testing the same program that I wrote. Testing
a different program is usually of no use whatever. It can even cause
trouble if you fail to tell me that you tested some other program
instead of what I know as GCC. I might think that GCC works, when in
fact it has not been properly tried, and might have a glaring fault.
* Even changing the compilation options counts as a change in the
program. The GCC sources specify which compilation options to use.
Some of them are specified in makefiles, and some in machine-specific
configuration files.
You have ways to override this--but if you do, then you are not
testing what ordinary users will do. Therefore, when pretesting, it
is vital to test with the default compilation options.
(It is okay to test with nonstandard options as well as testing with
the standard ones.)
* The machine and system configuration files of GCC are parts of
GCC. So when you test GCC, you need to do it with the
configuration files that come with GCC.
If GCC does not come with configuration files for a certain machine,
and you test it with configuration files that don't come with GCC,
this is effectively changing GCC. Because the crucial fact about
the planned release is that, without changes, it doesn't work on that
machine.
To make GCC work on that machine, I would need to install new
configuration files. That is not out of the question, since it is
safe--it certainly won't break any other machines that already work.
But you will have to rush me the legal papers to give the FSF
permission to use a large piece of text.
* Look for recommendations for your system.
You can find these recommendations in the Installation node of the
manual, and in the file INSTALL. (These two files have the same text.)
These files say which configuration name to use for your machine, so
use the ones that are recommended. If you guess, you might guess
wrong and encounter spurious difficulties. What's more, if you don't
follow the recommendations then you aren't helping to test that its
recommendations are valid.
These files may describe other things that you need to do to make GCC
work on your machine. If so, you should follow these recommendations
also, for the same reason.
Also look at the Trouble chapter of the manual for items that
pertain to your machine.
* Don't delay sending information.
When you find a problem, please double check it if you can do so
quickly. But don't spend a long time double-checking. A good rule is
always to tell me about every problem on the same day you encounter
it, even if that means you can't find a solution before you report the
problem.
I'd much rather hear about a problem today and a solution tomorrow
than get both of them tomorrow at the same time.
* Make each bug report self-contained.
If you refer back to another message, whether from you or from someone
else, then it will be necessary for anyone who wants to investigate
the bug to find the other message. This may be difficult, it is
probably time-consuming.
To help me save time, simply copy the relevant parts of any previous
messages into your own bug report.
In particular, if I ask you for more information because a bug report
was incomplete, it is best to send me the *entire* collection of
relevant information, all together. If you send just the additional
information, that makes me do extra work. There is even a risk that
I won't remember what question you are sending me the answer to.
* Always be precise when talking about changes you have made. Show
things rather than describing them. Use exact filenames (relative to
the main directory of the distribution), not partial ones. For
example, say "I changed Makefile" rather than "I changed the
makefile". Instead of saying "I defined the MUMBLE macro", send a
diff that shows your change.
* Always use `diff -c' to make diffs. If you don't include context,
it may be hard for me to figure out where you propose to make the
changes. I might have to ignore your patch because I can't tell what
it means.
* When you write a fix, keep in mind that I can't install a change
that would break other systems.
People often suggest fixing a problem by changing machine-independent
files such as toplev.c to do something special that a particular
system needs. Sometimes it is totally obvious that such changes would
break GCC for almost all users. I can't possibly make a change like
that. All I can do is send it back to you and ask you to find a fix
that is safe to install.
Sometimes people send fixes that *might* be an improvement in
general--but it is hard to be sure of this. I can install such
changes some of the time, but not during pretest, when I am trying to
get a new version to work reliably as quickly as possible.
The safest changes for me to install are changes to the configuration
files for a particular machine. At least I know those can't create
bugs on other machines.
* Don't try changing GCC unless it fails to work if you don't change it.
* Don't even suggest changes that would only make GCC cleaner.
Every change I install could introduce a bug, so I won't install
a change unless I see it is necessary.
* If you would like to suggest changes for purposes other than fixing
serious bugs, don't wait till pretest time. Instead, send them just
after I make a release. That's the best time for me to install them.
* In some cases, if you don't follow these guidelines, your
information might still be useful, but I might have to do more work to
make use of it. Unfortunately, I am so far behind in my work that I
just can't get the job done unless you help me to do it efficiently.
Thank you

This is a collection of things that test suites have
said were "wrong" with GCC--but that I don't agree with.
First, test suites sometimes test for compatibility with
traditional C. GCC with -traditional is not completely
compatible with traditional C, and in some ways I think it
should not be.
* K&R C allowed \x to appear in a string literal (or character
literal?) even in cases where it is *not* followed by a sequence of
hex digits. I'm not convinced this is desirable.
* K&R compilers allow comments to cross over an inclusion boundary (i.e.
started in an include file and ended in the including file).
I think this would be quite ugly and can't imagine it could
be needed.
Sometimes tests disagree with GCC's interpretation of the ANSI standard.
* One test claims that this function should return 1.
enum {A, B} foo;
func (enum {B, A} arg)
{
return B;
}
I think it should return 0, because the definition of B that
applies is the one in func.
* Some tests report failure when the compiler does not produce
an error message for a certain program.
ANSI C requires a "diagnostic" message for certain kinds of invalid
programs, but a warning counts as a diagnostic. If GCC produces
a warning but not an error, that is correct ANSI support.
When test suites call this "failure", the tests are broken.

.SH DESCRIPTION
The C preprocessor is a \c
.I macro processor\c
\& that is used automatically by
the C compiler to transform your program before actual compilation. It is
called a macro processor because it allows you to define \c
.I macros\c
\&,
which are brief abbreviations for longer constructs.
The C preprocessor provides four separate facilities that you can use as
you see fit:
.TP
\(bu
Inclusion of header files. These are files of declarations that can be
substituted into your program.
.TP
\(bu
Macro expansion. You can define \c
.I macros\c
\&, which are abbreviations
for arbitrary fragments of C code, and then the C preprocessor will
replace the macros with their definitions throughout the program.
.TP
\(bu
Conditional compilation. Using special preprocessing directives, you
can include or exclude parts of the program according to various
conditions.
.TP
\(bu
Line control. If you use a program to combine or rearrange source files into
an intermediate file which is then compiled, you can use line control
to inform the compiler of where each source line originally came from.
.PP
C preprocessors vary in some details. For a full explanation of the
GNU C preprocessor, see the
.B info
file `\|\c
.B cpp.info\c
\&\|', or the manual
.I The C Preprocessor\c
\&. Both of these are built from the same documentation source file, `\|\c
.B cpp.texinfo\c
\&\|'. The GNU C
preprocessor provides a superset of the features of ANSI Standard C.
ANSI Standard C requires the rejection of many harmless constructs commonly
used by today's C programs. Such incompatibility would be inconvenient for
users, so the GNU C preprocessor is configured to accept these constructs
by default. Strictly speaking, to get ANSI Standard C, you must use the
options `\|\c
.B \-trigraphs\c
\&\|', `\|\c
.B \-undef\c
\&\|' and `\|\c
.B \-pedantic\c
\&\|', but in
practice the consequences of having strict ANSI Standard C make it
undesirable to do this.
Most often when you use the C preprocessor you will not have to invoke it
explicitly: the C compiler will do so automatically. However, the
preprocessor is sometimes useful individually.
When you call the preprocessor individually, either name
(\c
.B cpp\c
\& or \c
.B cccp\c
\&) will do\(em\&they are completely synonymous.
The C preprocessor expects two file names as arguments, \c
.I infile\c
\& and
\c
.I outfile\c
\&. The preprocessor reads \c
.I infile\c
\& together with any other
files it specifies with `\|\c
.B #include\c
\&\|'. All the output generated by the
combined input files is written in \c
.I outfile\c
\&.
Either \c
.I infile\c
\& or \c
.I outfile\c
\& may be `\|\c
.B \-\c
\&\|', which as \c
.I infile\c
\&
means to read from standard input and as \c
.I outfile\c
\& means to write to
standard output. Also, if \c
.I outfile\c
\& or both file names are omitted,
the standard output and standard input are used for the omitted file names.
.SH OPTIONS
Here is a table of command options accepted by the C preprocessor.
These options can also be given when compiling a C program; they are
passed along automatically to the preprocessor when it is invoked by
the compiler.
.TP
.B \-P
Inhibit generation of `\|\c
.B #\c
\&\|'-lines with line-number information in
the output from the preprocessor. This might be
useful when running the preprocessor on something that is not C code
and will be sent to a program which might be confused by the
`\|\c
.B #\c
\&\|'-lines.
.TP
.B \-C
Do not discard comments: pass them through to the output file.
Comments appearing in arguments of a macro call will be copied to the
output before the expansion of the macro call.
.TP
.B \-traditional
Try to imitate the behavior of old-fashioned C, as opposed to ANSI C.
.TP
.B \-trigraphs
Process ANSI standard trigraph sequences. These are three-character
sequences, all starting with `\|\c
.B ??\c
\&\|', that are defined by ANSI C to
stand for single characters. For example, `\|\c
.B ??/\c
\&\|' stands for
`\|\c
.BR "\e" "\|',"
so `\|\c
.B '??/n'\c
\&\|' is a character constant for a newline.
Strictly speaking, the GNU C preprocessor does not support all
programs in ANSI Standard C unless `\|\c
.B \-trigraphs\c
\&\|' is used, but if
you ever notice the difference it will be with relief.
You don't want to know any more about trigraphs.
.TP
.B \-pedantic
Issue warnings required by the ANSI C standard in certain cases such
as when text other than a comment follows `\|\c
.B #else\c
\&\|' or `\|\c
.B #endif\c
\&\|'.
.TP
.B \-pedantic\-errors
Like `\|\c
.B \-pedantic\c
\&\|', except that errors are produced rather than
warnings.
.TP
.B \-Wtrigraphs
Warn if any trigraphs are encountered (assuming they are enabled).
.TP
.B \-Wcomment
.TP
.B \-Wcomments
Warn whenever a comment-start sequence `\|\c
.B /*\c
\&\|' appears in a comment.
(Both forms have the same effect).
.TP
.B \-Wall
Requests both `\|\c
.B \-Wtrigraphs\c
\&\|' and `\|\c
.B \-Wcomment\c
\&\|' (but not
`\|\c
.B \-Wtraditional\c
\&\|').
.TP
.B \-Wtraditional
Warn about certain constructs that behave differently in traditional and
ANSI C.
.TP
.BI "\-I " directory\c
\&
Add the directory \c
.I directory\c
\& to the end of the list of
directories to be searched for header files.
This can be used to override a system header file, substituting your
own version, since these directories are searched before the system
header file directories. If you use more than one `\|\c
.B \-I\c
\&\|' option,
the directories are scanned in left-to-right order; the standard
system directories come after.
.TP
.B \-I\-
Any directories specified with `\|\c
.B \-I\c
\&\|' options before the `\|\c
.B \-I\-\c
\&\|'
option are searched only for the case of `\|\c
.B #include "\c
.I file\c
\&"\c
\&\|';
they are not searched for `\|\c
.B #include <\c
.I file\c
\&>\c
\&\|'.
If additional directories are specified with `\|\c
.B \-I\c
\&\|' options after
the `\|\c
.B \-I\-\c
\&\|', these directories are searched for all `\|\c
.B #include\c
\&\|'
directives.
In addition, the `\|\c
.B \-I\-\c
\&\|' option inhibits the use of the current
directory as the first search directory for `\|\c
.B #include "\c
.I file\c
\&"\c
\&\|'.
Therefore, the current directory is searched only if it is requested
explicitly with `\|\c
.B \-I.\c
\&\|'. Specifying both `\|\c
.B \-I\-\c
\&\|' and `\|\c
.B \-I.\c
\&\|'
allows you to control precisely which directories are searched before
the current one and which are searched after.
.TP
.B \-nostdinc
Do not search the standard system directories for header files.
Only the directories you have specified with `\|\c
.B \-I\c
\&\|' options
(and the current directory, if appropriate) are searched.
.TP
.B \-nostdinc++
Do not search for header files in the C++ specific standard
directories, but do still search the other standard directories.
(This option is used when building libg++.)
.TP
.BI "\-D " "name"\c
\&
Predefine \c
.I name\c
\& as a macro, with definition `\|\c
.B 1\c
\&\|'.
.TP
.BI "\-D " "name" = definition
\&
Predefine \c
.I name\c
\& as a macro, with definition \c
.I definition\c
\&.
There are no restrictions on the contents of \c
.I definition\c
\&, but if
you are invoking the preprocessor from a shell or shell-like program
you may need to use the shell's quoting syntax to protect characters
such as spaces that have a meaning in the shell syntax. If you use more than
one `\|\c
.B \-D\c
\&\|' for the same
.I name\c
\&, the rightmost definition takes effect.
.TP
.BI "\-U " "name"\c
\&
Do not predefine \c
.I name\c
\&. If both `\|\c
.B \-U\c
\&\|' and `\|\c
.B \-D\c
\&\|' are
specified for one name, the `\|\c
.B \-U\c
\&\|' beats the `\|\c
.B \-D\c
\&\|' and the name
is not predefined.
.TP
.B \-undef
Do not predefine any nonstandard macros.
.TP
.BI "\-A " "name(" value )
Assert (in the same way as the \c
.B #assert\c
\& directive)
the predicate \c
.I name\c
\& with tokenlist \c
.I value\c
\&. Remember to escape or quote the parentheses on
shell command lines.
You can use `\|\c
.B \-A-\c
\&\|' to disable all predefined assertions; it also
undefines all predefined macros.
.TP
.B \-dM
Instead of outputting the result of preprocessing, output a list of
`\|\c
.B #define\c
\&\|' directives for all the macros defined during the
execution of the preprocessor, including predefined macros. This gives
you a way of finding out what is predefined in your version of the
preprocessor; assuming you have no file `\|\c
.B foo.h\c
\&\|', the command
.sp
.br
touch\ foo.h;\ cpp\ \-dM\ foo.h
.br
.sp
will show the values of any predefined macros.
.TP
.B \-dD
Like `\|\c
.B \-dM\c
\&\|' except in two respects: it does \c
.I not\c
\& include the
predefined macros, and it outputs \c
.I both\c
\& the `\|\c
.B #define\c
\&\|'
directives and the result of preprocessing. Both kinds of output go to
the standard output file.
.PP
.TP
.BR \-M\ [ \-MG ]
Instead of outputting the result of preprocessing, output a rule
suitable for \c
.B make\c
\& describing the dependencies of the main
source file. The preprocessor outputs one \c
.B make\c
\& rule containing
the object file name for that source file, a colon, and the names of
all the included files. If there are many included files then the
rule is split into several lines using `\|\c
.B \\\\\c
\&\|'-newline.
`\|\c
.B \-MG\c
\&\|' says to treat missing header files as generated files and assume \c
they live in the same directory as the source file. It must be specified \c
in addition to `\|\c
.B \-M\c
\&\|'.
This feature is used in automatic updating of makefiles.
.TP
.BR \-MM\ [ \-MG ]
Like `\|\c
.B \-M\c
\&\|' but mention only the files included with `\|\c
.B #include
"\c
.I file\c
\&"\c
\&\|'. System header files included with `\|\c
.B #include
<\c
.I file\c
\&>\c
\&\|' are omitted.
.TP
.BI \-MD\ file
Like `\|\c
.B \-M\c
\&\|' but the dependency information is written to `\|\c
.I file\c
\&\|'. This is in addition to compiling the file as
specified\(em\&`\|\c
.B \-MD\c
\&\|' does not inhibit ordinary compilation the way
`\|\c
.B \-M\c
\&\|' does.
When invoking gcc, do not specify the `\|\c
.I file\c
\&\|' argument. Gcc will create file names made by replacing `\|\c
.B .c\c
\&\|' with `\|\c
.B .d\c
\&\|' at the end of the input file names.
In Mach, you can use the utility \c
.B md\c
\& to merge multiple files
into a single dependency file suitable for using with the `\|\c
.B make\c
\&\|'
command.
.TP
.BI \-MMD\ file
Like `\|\c
.B \-MD\c
\&\|' except mention only user header files, not system
header files.
.TP
.B \-H
Print the name of each header file used, in addition to other normal
activities.
.TP
.BI "\-imacros " "file"\c
\&
Process \c
.I file\c
\& as input, discarding the resulting output, before
processing the regular input file. Because the output generated from
\c
.I file\c
\& is discarded, the only effect of `\|\c
.B \-imacros \c
.I file\c
\&\c
\&\|' is to
make the macros defined in \c
.I file\c
\& available for use in the main
input. The preprocessor evaluates any `\|\c
.B \-D\c
\&\|' and `\|\c
.B \-U\c
\&\|' options
on the command line before processing `\|\c
.B \-imacros \c
.I file\c
\&\|' \c
\&.
.TP
.BI "\-include " "file"
Process
.I file
as input, and include all the resulting output,
before processing the regular input file.
.TP
.BI "-idirafter " "dir"\c
\&
Add the directory \c
.I dir\c
\& to the second include path. The directories
on the second include path are searched when a header file is not found
in any of the directories in the main include path (the one that
`\|\c
.B \-I\c
\&\|' adds to).
.TP
.BI "-iprefix " "prefix"\c
\&
Specify \c
.I prefix\c
\& as the prefix for subsequent `\|\c
.B \-iwithprefix\c
\&\|'
options.
.TP
.BI "-iwithprefix " "dir"\c
\&

handle C++ comment syntax, and includes extra default include
directories for C++, and `\|\c
.B \-lang-objc\c

`\|\c

\&\|' directive. `\|\c
.B \-lang-c\c
\&\|' explicitly turns off both of
these extensions, and `\|\c
.B \-lang-objc++\c

These options are generated by the compiler driver \c
.B gcc\c

passed from the `\|\c
.B gcc\c
\&\|' command line.
.TP
.B \-lint
Look for commands to the program checker \c
.B lint\c
\& embedded in
comments, and emit them preceded by `\|\c
.B #pragma lint\c
\&\|'. For example,
the comment `\|\c
.B /* NOTREACHED */\c
\&\|' becomes `\|\c
.B #pragma lint
NOTREACHED\c
\&\|'.
This option is available only when you call \c
.B cpp\c
\& directly;
\c
.B gcc\c
\& will not pass it from its command line.
.TP
.B \-$
Forbid the use of `\|\c
.B $\c

to the C Standard before the standard was corrected. \c

1 GCC
The GCC command invokes the GNU C compiler.
GCC file-spec
2 Parameters
file-spec
A C source file. If no input file extension is specified, GNU C
assumes .C as the default extension unless the /PLUS qualifier is
given, in which case .CC is assumed as the default extension.
If an extension of .CPP is given, then the source file is assumed to
be the output of the preprocessor, and thus the preprocessor is not
executed.
If an extension of .S is given, then the source file is assumed to be
the assembly code output of the compiler, and only the assembler is
called to generate an object file.
2 Qualifiers
GNU C command qualifiers modify the way the compiler handles the
compilation.
The following is the list of available qualifiers for GNU C:
/CASE_HACK
/CC1_OPTIONS=(option [,option...]])
/DEBUG
/DEFINE=(identifier[=definition][,...])
/G_FLOAT
/INCLUDE_DIRECTORY=(path [,path...]])
/LIST[=filename]
/MACHINE_CODE
/OBJECT[=filename]
/OPTIMIZE
/PLUS
/PROFILE[=identifier]
/SCAN=(file[,file...])
/SHOW[=option]
/UNDEFINE=(identifier[,identifier,...])
/VERBOSE
/VERSION
/WARNING
2 Linking
When linking programs compiled with GNU C, you should include the GNU
C library before the VAX C library. For example,
LINK object-file,GNU_CC:[000000]GCCLIB/LIB,SYS$LIBRARY:VAXCRTL/LIB
You can also link your program with the shared VAX C library. This
can reduce the size of the .EXE file, as well as make it smaller when
it's running. For example,
$ LINK object-file, GNU_CC:[000000]GCCLIB/LIB,SYS$INPUT/OPT
SYS$SHARE:VAXCRTL/SHARE
(If you use the second example and type it in by hand, be sure to
type ^Z after the last carriage return). A simpler alternative would
be to place the single line:
SYS$SHARE:VAXCRTL/SHARE
into a file called VAXCRTL.OPT, and then use the link command:
$ LINK object-file, GNU_CC:[000000]GCCLIB/LIB,VAXCRTL.OPT/OPT
If a program has been compiled with /G_FLOAT, then the linking
instructions are slightly different. If you are linking with the
non-shared library, then the command that you should use would be:
LINK object-file,GNU_CC:[000000]GCCLIB/LIB,SYS$LIBRARY:VAXCRTLG/LIB -
,SYS$LIBRARY:VAXCRTL/LIB
Note that both VAXCRTL and VAXCRTLG must be linked to. If you are
using the shared VAX C library, then you should use a command like:
$ LINK object-file, GNU_CC:[000000]GCCLIB/LIB,SYS$INPUT:/OPTIONS
SYS$SHARE:VAXCRTLG/SHARE
In the case of the sharable library, only one library needs to be
linked to.
If you need to link to libg++, it is easiest to use the command
procedure supplied with libg++ to link your program.
2 /CASE_HACK
/[NO]CASE_HACK D=/CASE_HACK
Since the VMS Linker and Librarian are not case sensitive with
respect to symbol names, a "case-hack" is appended to a symbol name
when the symbol contains upper case characters.
There are cases where this is undesirable, (mainly when using certain
applications where modules have been precompiled, perhaps in another
language) and we want to compile without case hacking. In these
cases the /NOCASE_HACK switch disables case hacking.
2 /CC1_OPTIONS
This specifies additional switches to the compiler itself which
cannot be set by means of the compiler driver.
2 /DEBUG
/DEBUG includes additional information in the object file output so
that the program can be debugged with the VAX Symbolic Debugger.
To use the debugger it is also necessary to link the debugger to your
program, which is done by specifying the /DEBUG qualifier to the link
command. With the debugger it is possible to set breakpoints,
examine variables, and set variables to new values. See the VAX
Symbolic Debugger manual for more information, or type "HELP" from
the debugger prompt.
2 /DEFINE
/DEFINE=(identifier[=definition][,...])
/DEFINE defines a string or macro ('definition') to be substituted
for every occurrence of a given string ('identifier') in a program.
It is equivalent to the #define preprocessor directive.
All definitions and identifiers are converted to uppercase unless
they are in quotation marks.
The simple form of the /DEFINE qualifier:
/DEFINE=vms
results in a definition equivalent to the preprocessor directive:
#define VMS 1
You must enclose macro definitions in quotation marks, as in this
example:
/DEFINE="C(x)=((x) & 0xff)"
This definition is the same as the preprocessor definition:
#define C(x) ((x) & 0xff)
If more than one /DEFINE is present on the GCC command line, only the
last /DEFINE is used.
If both /DEFINE and /UNDEFINE are present on a command line, /DEFINE
is evaluated before /UNDEFINE.
2 /G_FLOAT
Instructs the compiler to use "G" floating point arithmetic instead
of "D". The difference is that double precision has a range of
approximately +/-0.56e-308 to +/-0.9 e+308, with approximately 15
decimal digits precision.
"D" floating point has the same range as single precision floating
point, with approximately 17 decimal digits precision.
If you use the /G_FLOAT qualifier, the linking instructions are
different. See "Linking" for further details.
2 /LIST
/LIST[=list_file_name]
This does not generate a listing file in the usual sense, however it
does direct the compiler to save the preprocessor output. If a file
is not specified, then this output is written into a file with the
same name as the source file and an extension of .CPP.
2 /INCLUDE_DIRECTORY
/INCLUDE_DIRECTORY=(path [,path...])
The /INCLUDE_DIRECTORY qualifier provides additional directories to
search for user-defined include files. 'path' can be either a
logical name or a directory specification.
There are two forms for specifying include files - #include
"file-spec" and #include <file-spec>. For the #include "file-spec"
form, the search order is:
1. The directory containing the source file.
2. The directories in the /INCLUDE qualifier (if any).
3. The directory (or directories) specified in the logical name
GNU_CC_INCLUDE.
4. The directory (or directories) specified in the logical name
SYS$LIBRARY.
For the #include <file-spec> form, the search order is:
1. The directories specified in the /INCLUDE qualifier (if any).
2. The directory (or directories) specified in the logical name
GNU_CC_INCLUDE.
3. The directory (or directories) specified in the logical name
SYS$LIBRARY.
2 /MACHINE_CODE
Tells GNU C to output the machine code generated by the compiler.
The machine code is output to a file with the same name as the input
file, with the extension .S. An object file is still generated,
unless /NOOBJ is also specified.
2 /OBJECT
/OBJECT[=filename]
/NOOBJECT
Controls whether or not an object file is generated by the
compiler.
2 /OPTIMIZE
/[NO]OPTIMIZE
Controls whether optimization is performed by the compiler. By
default, optimization is on. /NOOPTIMIZE turns optimization off.
2 /PLUS
Instructs the compiler driver to use the GNU-C++ compiler instead of
the GNU-C compiler. Note that the default extension of source files
is .CC when this qualifier is in effect.
2 /PROFILE
/PROFILE[=identifier]
Instructs the compiler to generate function profiling code. You must
link your program to the profiler when you use this options. The
profile statistics are automatically printed out on the terminal
during image exit. (i.e. no modifications to your source file are
required in order to use the profiler).
There are three identifiers that can be used with the /PROFILE
switch. These are ALL, FUNCTION, and BLOCK. If /PROFILE is given
without an identifier, then FUNCTION is assumed.
3 Block_Profiler
The block profiler counts how many times control of the program
passes certain points in your program. This is useful in determining
which portions of a program would benefit from recoding for
optimization.
The report for the block profiler contains the function name, file
name, PC, and the source file line number as well as the count of how
many times control has passed through the specified source line.
3 Function_Profiler
The function profiler counts how many times each function is entered,
and keeps track of how much CPU time is used within each function.
You should be careful about interpreting the results of profiles
where there are inline functions. When a function is included as
inline, then there is no call to the internal data collection routine
used by the profiler, and thus there will be no record of this
function being called. The compiler does generate a callable version
of each inline function, and if this called version is used, then the
profiler's data collection routine will be called.
2 /SCAN
/SCAN=(file[,file...])
This qualifier supplies a list of files that will be read as input,
and the output will be discarded before processing the regular input
file. Because the output generated from the files is discarded, the
only effect of this qualifier is to make the macros defined in the
files available for use in the main input.
2 /SHOW
/SHOW[=option]
This causes the preprocessor to generate information other than the
preprocessed input file. When this qualifier is used, no assembly
code and no object file is generated.
The output of the preprocessor is placed in the file specified by the
/LIST qualifier, if present. If the /LIST qualifier is not present,
then the output is placed in a file with the same name as the input
file with an extension that depends upon which option that is
selected.
3 DEFINITIONS
This option causes the preprocessor to dump a list of all of the
definitions to the output file. This is useful for debugging
purposes, since it lets you determine whether or not everything has
been defined properly.
If the default file name is used for the output, the extension will
be .DEF.
3 RULES
This option causes the preprocessor to output a rule suitable for
MAKE, describing the dependencies of the main source file. The
preprocessor outputs one MAKE rule containing the object file name
for that source file, a colon, and the names of all the concluded
files. If there are many included files then the rule is split into
several lines using the '\'-newline.
When using this option, only files included with the "#include "file"
directive are mentioned.
If the default file name is used for the output, a null extension
will be used.
3 ALL
This option is similar to RULES, except that it also mentions files
included with the "#include <file.h>" directive.
If the default file name is used for the output, a null extension
will be used.
2 /UNDEFINE
/UNDEFINE cancels a macro definition. Thus, it is the same as the
#undef preprocessor directive.
If more than one /UNDEFINE is present on the GCC command line, only
the last /UNDEFINE is used.
If both /DEFINE and /UNDEFINE are present on a command line, /DEFINE
is evaluated before /UNDEFINE.
2 /VERBOSE
Controls whether the user sees the invocation command strings for the
preprocessor, compiler, and assembler. The compiler also outputs
some statistics on time spent in its various phases.
2 /VERSION
Causes the preprocessor and the compiler to identify themselves by
their version numbers, and in the case of the compiler, the version
number of the compiler that built it.
2 /WARNING
When this qualifier is present, warnings about usage that should be
avoided are given by the compiler. For more information, see "Using
and Porting GNU CC", in the section on command line options, under
"-Wall".
Warnings are also generated by the preprocessor when this qualifier
is given.
2 Known_Incompatibilities_with_VAX-C
There are several known incompatibilities between GNU-C and VAX-C.
Some common ones will be briefly described here. A complete
description can be found in "Using and Porting GNU CC" in the chapter
entitled "Using GNU CC on VMS".
GNU-C provides case hacking as a means of giving case sensitivity
to symbol names. The case hack is a hexadecimal number appended to
the symbol name, with a bit being set for each upper case letter.
Symbols with all lower case, or symbols that have a dollar sign ("$")
are not case hacked. There are times that this is undesirable,
namely when you wish to link your program against a precompiled
library which was compiled with a non-GNU-C compiler. X-windows (or
DECWindows) is an example of this. In these instances, the
/NOCASE_HACK switch should be used.
If you require case hacking in some cases, but not in others (i.e.
Libg++ with DECWindows), then it is recommended that you develop a
header file which will define all mixed case functions that should
not have a case hack as the lower case equivalents.
GNU-C does not provide the globaldef and globalref mechanism
which is used by VAX-C to coerce the VMS linker to include certain
object modules from a library. There are assembler hacks, which are
available to the user through the macros defined in gnu_hacks.h,
which effectively give you the ability to perform these functions.
While not syntactically identical, they do provide most of the
functionality.
Note that globaldefs of enums is not supported in the way that it is
under VAX-C. This can be easily simulated, however, by globaldefing
an integer variable, and then globalvaluing all of the enumerated
states.
Furthermore, the way that globalvalue is currently implemented, the
data type of the globalvalue variable is seen to the compiler to be a
pointer to the data type that you specify. This is necessary in
order to make the compiler correctly address the globalvalue
variables.

@item -fprofile-arcs
Instrument @dfn{arcs} during compilation. For each function of your
program, GNU CC creates a program flow graph, then finds a spanning tree
for the graph. Only arcs that are not on the spanning tree have to be
instrumented: the compiler adds code to count the number of times that these
arcs are executed. When an arc is the only exit or only entrance to a
block, the instrumentation code can be added to the block; otherwise, a
new basic block must be created to hold the instrumentation code.
Since not every arc in the program must be instrumented, programs
compiled with this option run faster than programs compiled with
@samp{-a}, which adds instrumentation code to every basic block in the
program. The tradeoff: since @code{gcov} does not have
execution counts for all branches, it must start with the execution
counts for the instrumented branches, and then iterate over the program
flow graph until the entire graph has been solved. Hence, @code{gcov}
runs a little more slowly than a program which uses information from
@samp{-a}.
@samp{-fprofile-arcs} also makes it possible to estimate branch
probabilities, and to calculate basic block execution counts. In
general, basic block execution counts do not give enough information to
estimate all branch probabilities. When the compiled program exits, it
saves the arc execution counts to a file called
@file{@var{sourcename}.da}. Use the compiler option

Position-independent code requires special support, and therefore works

but not for the Sun 386i. Code generated for the IBM RS/6000 is always
position-independent.

Generate extra code to check each memory access. GNU CC will generate
code that is suitable for a detector of bad memory accesses such as

You must also specify this option when you compile functions you call that

the detector. Normally, you should compile all your code with this option.
If you use functions from a library that have side-effects (such as
@code{read}), you may not be able to recompile the library and
specify this option. In that case, you can enable the
@samp{-fprefix-function-name} option, which requests GNU CC to encapsulate
your code and make other functions look as if they were compiled with
@samp{-fcheck-memory-usage}. This is done by calling ``stubs'',
which are provided by the detector. If you cannot find or build
stubs for every function you call, you may have to specify
@samp{-fcheck-memory-usage} without @samp{-fprefix-function-name}.
