2004-02-29  Sebastian Wilhelmi  <seppi@seppi.de>

	* configure.in, glib/gatomic.c, glib/gatomic.h: Moved the
	assembler functions from gatomic.h to gatomic.c, which makes for
	better maintainability. Also use gint instead of gint32 to be able
	to use reference counting for ABI-fixed structures with
	gint/guint.

	* glib/gthread.h: Adapted accordingly.

	* tests/atomic-test.c: Updated to test for G_MAXINT and G_MININT.

	* glib/glib-overrides.txt, glib/glib-sections.txt,
	glib/tmpl/atomic_operations.sgml: Updated according to code changes.
