Do not use the thread libs, when searching for some functions, as this

	* configure.in: Do not use the thread libs, when searching for
	some functions, as this might require glib to always be linked
	with the thread libs on some platforms.

	* gutils.c (g_get_any_init): Don't set errno to zero and use it
	only as the error code, if the function returned a value less
	0. It might happen, that the call succeeds, even though the errno
	is set during the call (i.e. it first looks for a passwd file,
	which is not found). Submitted by Michael Natterer
	<mitschel@cs.tu-berlin.de>. BTW: Sorry for all the mess with that
	`getpwuid_r' change, but it had to be done once.
