@chapter Other Directives

The @samp{#ident} directive takes one argument, a string constant. On
some systems, that string constant is copied into a special segment of
the object file. On other systems, the directive is ignored.

@samp{#sccs} directive is a synonym for @samp{#ident}.
This directive is not part of the C standard, but it is not an official
GNU extension either. We believe it came from System V@.
@findex #sccs
The @samp{#sccs} directive is recognized, because it appears in the
header files of some systems. It is a very old, obscure, extension
which we did not invent, and we have been unable to find any
documentation of what it should do, so GCC simply ignores it.
These directives are not part of the C standard, but they are not
official GNU extensions either. What historical information we have
been able to find, suggests they originated with System V@.
@cindex null directive
The @dfn{null directive} consists of a @samp{#} followed by a newline,
