[PATCH] Fix <semaphore.h>

[PATCH] Fix <semaphore.h>

[Jakub Jelinek]

Hi!

echo '#include <semaphore.h>' | gcc -std=c99 -xc -
fails because <bits/types.h> has:
/* Now add the thread types.  */
#if defined __USE_POSIX199506 || defined __USE_UNIX98
# include <bits/pthreadtypes.h>
#endif
so for ISO C99 _pthread_fastlock is not defined.
Below is one solution (assuming semaphore.h can bring in pthread types),
alternatively something like #ifdef _PTHREAD_FASTLOCK_DEFINED could be
used).

	* semaphore.h: Include bits/pthreadtypes.h.

Which is OK since <semaphore.h> is no C99 header.  Code which uses the
POSIX header must add the appropriate feature select macros.
