GCC modified for the FreeChainXenon project

The recursive_init_error class is defined in a header, with an inline constructor, but the definition of the vtable and destructor are not exported from the shared library. With -fkeep-inline-functions the constructor gets emitted in user code, and requires the (non-exported) vtable. This fails to link. As far as I can tell, the recursive_init_error class definition was moved into <cxxabi.h> so it could be documented with Doxygen, not for any technical reason. But now it's there (and documented), somebody could be relying on it, by catching that type and possibly performing derived-to-base conversions to the std::exception base class. So the conservative fix is to leave the class definition in the header but make the constructor non-inline. This still allows the type to be caught and still defines its base class. User code can no longer construct objects of that type, but that's not something we need to support. PR libstdc++/51333 * libsupc++/cxxabi.h (__gnu_cxx::recursive_init_error): Do not define constructor inline. * libsupc++/guard_error.cc (__gnu_cxx::recursive_init_error): Define constructor. * testsuite/18_support/51333.cc: New test.

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.
