When deduction guides are supported by the compiler (i.e. for C++17 and later) replace two basic_string constructors by constrained function templates as required by LWG 3075. In order to ensure that the pre-C++17 non-template constructors are still exported from the shared library define a macro in src/c++11/string-inst.cc to force the non-template declarations (this isn't strictly needed yet, because the string instantiations are compiled with -std=gnu++11, but that is likely to change). LWG 3076 basic_string CTAD ambiguity * doc/xml/manual/intro.xml: Document LWG 3076 change. * include/bits/basic_string.h [__cpp_deduction_guides && !_GLIBCXX_DEFINING_STRING_INSTANTIATIONS] (basic_string(const _CharT*, const _Alloc&)): Turn into a function template constrained by _RequireAllocator. (basic_string(size_type, _CharT, const _Alloc&)): Likewise. * src/c++11/string-inst.cc (_GLIBCXX_DEFINING_STRING_INSTANTIATIONS): Define. * testsuite/21_strings/basic_string/cons/char/deduction.cc: Test deduction * testsuite/21_strings/basic_string/cons/wchar_t/deduction.cc: Likewise.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
