Added the missing POSIX_NO_YIELD and POSIX_NO_PRIORITIES warning messages.
2000-03-17 Sebastian Wilhelmi <wilhelmi@ira.uka.de> * configure.in: Added the missing POSIX_NO_YIELD and POSIX_NO_PRIORITIES warning messages. * configure.in: Use AC_TRY_RUN instead of AC_TRY_LINK, to test for real thread support. On solaris pthread_create can be linked to even in -lc, but it doesn't work then. * configure.in: Don't use priorities for threads, when the minimal/maximal priorities couldn't be determined at configure time. * configure.in, gthread.c: Always define GSystemThread in glibconfig.h to represent a system thread. * configure.in: Do not use native recursive threads, when possibe. We use some features, that they do not expose (namely the depth counter). * glib.h, gthread.c: Redefined GStaticRecMutex. The functions are now implemented in a different way, which should be way faster. Alsothere are now functions g_static_rec_mutex_unlock_full and g_static_rec_mutex_lock_full to leave/enter a recursive mutex completly. * gthread.c (g_thread_self): Do not test the system_thread to be non-zero to speed things up. * gthread.c (g_mutex_init): Therefore set the system_thread of the main thread here. * tests/thread-test.c: Rerun all tests once again, but this time we fool the system into thinking, that the available thread system is not native, but userprovided. * gthread/gthread-posix.c: Don't use priorities for threads, when the minimal/maximal priorities couldn't be determined at configure time. * gthread/gthread-posix.c: Don't check for errors, when setting the scope of a tread to system, as some posix implementations can't do that and we don't want the thing to fail because of that.
