That should fix his __attribute__ issue, but I still see a minor
problem with libc/posix/sys/types.h. When a non-GCC compiler is used,
it typedefs int8_t to plain 'char', which is incorrect if char is
I just checked, and OpenBSD 4.0 <sys/types.h> and <stdint.h> both
typedef int8_t to 'signed char' unconditionally. Solaris 10
<sys/types.h> and <stdint.h> both typedef int8_t to plain 'char' if
char is signed, else to 'signed char' if C89 or later, else they leave
int8_t undefined. Both approaches work; the former is simpler. So
how about this patch?

* posix/sys/types.h (int8_t) [!__GNUC_PREREQ (2, 7)]:
Typedef to signed char, not to plain char, so that code
using int8_t operates correctly when char is unsigned.
