Moved determination of G_THREAD_FLAGS before G_THREAD_LIBS. Check for

2000-09-28  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* configure.in: Moved determination of G_THREAD_FLAGS before
	G_THREAD_LIBS. Check for UnixWare systems and set the right cflags
	and libs there (it needs -Kthread for the native compiler and
	-pthread for gcc). Thanks to Boyd Lynn Gerber <gerberb@zenez.com>
	for the info.

	* configure.in: Fail immediately, when no thread library is found,
	instead of continuing searching for rt libs etc. Changed almost
	all occurances of $enable_threads to $have_threads, as that's,
	what we want.

	* tests/threadpool-test.c: Define vars inside the guard to avoid
	warnings.
