haiku/headers/build/gcc-2.95.3/stddef.h
Ingo Weinhold 404a0fea46 Second stab at reorganizing standard/gcc headers. This time it not only 
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.
