Test for sched_yield as the native yield function first. Corrected typo
2000-03-22 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Test for sched_yield as the native yield function
first. Corrected typo g_thread_sleep -> g_usleep. Corrected
message for the pthread_create test. Negative Priorities are
allowed (and used on Solaris), so consider
sched_get_priority_min failed only if it returns -1, not <0. Check
for sched_get_priority_min also in -lrt, if not found in -lpthread
alone and add -lrt to G_THREAD_LIBS then. Remove special case
handling of priorities for older solaris versions and posix
threads. Thanks to Wan-Teh Chang <wtc@netscape.com> for suggesting
some of those changes.
* config.guess, config.sub, ltconfig, ltmain.sh:
Upgrade to libtool 1.3.4.
