Don't link glib against libpthread. (#393812)

2007-01-07  Matthias Clasen  <mclasen@redhat.com>

	Don't link glib against libpthread.  (#393812)
	
	* configure.in: Link gthread against librt, not glib itself.

	* glib/gthread.h:
	* glib/gthread.c: Add a new thread function, gettime.

	* glib/gtimer.c: Use gettime instead of directly working with
	the various system interfaces.

	* gthread/gthread-impl.c:
	* gthread/gthread-posix.c:
	* gthread/gthread-win32.c: Implement gettime.
