  Bug #23294: Detection of sem_xxx functions on NetBSD broken and \
  	DragonflyBSD misc patches
  
  Add the original intended test, since our current test for sched_yield
  is insufficient to copy.

  configure.in@stripped, 2007-05-08 09:18:49-04:00, cmiller@stripped +3 -0
    We can't check for sched_yield, as that is in libc on FBSD.
    
    Re-add the check for sem_init in librt.

# This is a BitKeeper patch.  What follows are the unified diffs for the
# set of deltas contained in the patch.  The rest of the patch, the part
# that BitKeeper cares about, is below these diffs.
