Hi,
It was reported to me that the use of module 'stdint' on Linux/libc5 with
gcc-2.7.2.1 gives an error. The reason is that <sys/bitypes.h>, included
by <sys/types.h>, already defines int8_t, int16_t and int32_t.
Here's a proposed fix, that I will send to the reporter for testing.

* m4/stdint.m4 (gl_STDINT_H): Also test for <sys/bitypes.h>.
* lib/stdint_.h: On Linux libc4 and libc5, include <sys/bitypes.h>
and don't define _STDINT_H_NEED_SIGNED_INT_TYPES.
