	* glib.h, gcache.c, gtree.c: Changed the 'value' parameter of
	g_cache_remove from gpointer to gconstpointer. Dito for the 'key'
	parameter of g_tree_lookup and g_tree_remove and the 'data'
	parameter of g_tree_serach. This function now takes a function of
	type GCompareFunc instead of GSearchFunc.

	* glib.h: Removed declaration of GSearchFunc.

	* gmem.c: s/GSearchFunc/GCompareFunc/.
