[PATCH] Add stdint.h #4

Closed jbruchon closed 8 years ago

jbruchon commented 9 years ago

I'm leaving this here because pull requests won't let me cherry-pick it at this point. Compiling some programs for ELKS doesn't work because bcc doesn't include the C99 stdint.h header. This patch provides one. While bcc is obviously not a C99-compliant compiler, this header is used by a lot of programs today (including ones I wrote) and there's no good reason I can think of not to have it.

Subject: [PATCH] Add stdint.h header to recognize some C99 types

Note that this header is not 100% compatible with Linux targets.
No one uses bcc to make Linux executables these days, and the
only incompatibility is that a macro that gets the maximum of
size_t will return a value that's too low.

Applied, thanks.
