builds on Linux with gcc 2 and 4, but the images do even run. :-) Not tested on BeOS. * Removed stddef.h and stdarg.h. They are provided by the compiler. * Adjusted size_t.h, wchar_t.h, and wchar.h accordingly. * Made stdio.h avoid gcc 2.95.3's fixincludes hack stdio_va_list * Added gcc 2.95.3 headers to the repository. They are used instead of the headers of the gcc 2.95.3's we use to compile Haiku with. Should avoid build problems with the BeOS native compiler. For sake of personal recreation you can rebuild the cross gcc 2.95.3, but the only thing that changed is its header directory (lib/gcc-lib/.../include), which isn't used anymore. Replacing it with headers/build/gcc-2.95.3 should have the same effect as rebuilding, BTW. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24413 a95241bf-73f2-0310-859d-f6bbb57e9c96
