Hi Richardm,

The _NP suffix means non-posix, and is generally used for system-specific
features. The use of "adaptive" mutexes is probably just an optimization,
so it should be completely safe to just comment it out on systems where
the macro doesn't exist (assuming it's a macro).
thank you, it must be optional:
#if (defined(LINUX) && (__GLIBC__ > 2) || (__GLIBC__ == 2 &&
__GLIBC_MINOR__ >= 2)) || \
(defined(FREEBSD) && __FreeBSD_version > 700055)
rv = pthread_mutexattr_settype(&_pt_mattr, PTHREAD_MUTEX_ADAPTIVE_NP);
PR_ASSERT(0 == rv);
#endif
does HURD define LINUX? somehow counterintuitive, I'd expect only GNU,
but not LINUX: would help in these situations
