If you're touching VxWorks stdint.h perhaps you could also define the
relevant target macros for GCC to have built-in knowledge of the types?
This is needed for the Fortran C bindings to work correctly, at least, and
ensures char16_t and char32_t (C11/C++11) are correct as well. (You could
then set use_gcc_stdint to "wrap" in config.gcc if you want to use GCC's
stdint.h for freestanding compilations.)
I would be happy to, but I'm not aware of what macros those are. If you could
point me to some documentation or explain to me what macros I need to define
I'll update the patch.
<http://gcc.gnu.org/ml/gcc/2009-04/msg00000.html> was my original
announcement for target OS maintainers. You should define the same set of
macros as in gcc/config/glibc-stdint.h (but, obviously, to values
appropriate to VxWorks), plus INTMAX_TYPE and UINTMAX_TYPE if the default
values of those macros are wrong for VxWorks, and make sure all the
c99-stdint-*.c tests pass.
Since u?int.*_t are already defined, would this work? Or should I use
the non-typedef'd versions? Also, I'm not exactly sure how to run the
regression tests with a cross compiler. I'm still new to everything,
bear with me :-)
