PTHREAD_THREADS_MAX not needed?

[Jeff Johnson]

(from bug 3156 comment 14) there's a devchk complaint about
PTHREAD_THREADS_MAX.

POSIX does describe this:

     {PTHREAD_THREADS_MAX}
         Maximum number of threads that can be created per process.
         Minimum Acceptable Value: {_POSIX_THREAD_THREADS_MAX}

and we have it:

/opt/lsb/include/limits.h:#define PTHREAD_THREADS_MAX 16384

but glibc doesn't use it this way, only the sysconf value makes sense:

/* The number of threads per process. */
#define _POSIX_THREAD_THREADS_MAX 64
/* We have no predefined limit on the number of threads. */
#undef PTHREAD_THREADS_MAX

(that is, sysconf(_SC_THREAD_THREADS_MAX) will give you a usable value at
runtime)

what should we do here?
