Check for timegm.

2006-03-23  Emmanuele Bassi  <ebassi@cvs.gnome.org>

	* configure.in: Check for timegm.

	* glib/gtimer.h:
	* glib/gtimer.c:
	* glib/glib.symbols:
	* docs/reference/glib/glib-sections.txt: Added g_time_val_to_iso8601
	and g_time_val_from_iso8601, to convert a GTimeVal to and from an
	ISO 8601 encoded date.

	* tests/testglib.c: Added test cases for g_time_val_to_iso8601()
	and g_time_val_from_iso8601() functions.
