	What platform was this compiled on?  AIX < 4.3.0 only has
libpthreads.a with the plural.  That is why there is a check.  AIX 4.3+
links libpthread.a to libpthreads.a.  This should not have been a
problem with current glib.  It builds just fine here (4.3.2 and 4.1.4
machines).

	AIX is one of the forefront POSIX boxes.  However, AIX 4.1.5 is
rather old and isn't quite the best development platform.  It doesn't
even have dlopen().  AIX 4.2.0 and greater have the same #define
PTHREAD_CREATE_JOINABLE 0 that Suns have.  I aim all my AIX portability towards
4.1.5 and greater, but if PTHREAD_CREATE_JOINABLE is required (as opposed to
PTHREAD_CREATE_UNDETACHED, which also defines to 0 and exists on AIX 4.1.5), I 
might but that to 4.2.1 and greater.
	Btw, if you have a choice, don't use gcc on AIX.  Gcc produces rather
bad object code on this platform.
