and further down in `# ifdef __GNUC__'

#   ifdef _REENTRANT
#     define __STL_THREADS
#   endif
#   ifdef _PTHREADS
#     define __STL_PTHREADS
#   endif

some duplication and inconsistency.

I didn't notice this problem but it further confirms that threads-posix.h
shouldn't muck with a define that is normally a compiler define.
