For the PID thread priorities surrogate use gettid instead of getpid. This

2004-02-25  Sebastian Wilhelmi  <seppi@seppi.de>

	* configure.in, glib/gthread.c: For the PID thread priorities
	surrogate use gettid instead of getpid. This also works with nptl
	(on linux-2.6), as well as with linuxthreads (on linux-2.4).
