	* configure.in: added a new conditional CROSS_COMPILING which
	indicates ($build != $host). If it is set, look for
	gdk-pixbuf-csource in PATH. Error out if it was not found.

	* gtk/stock-icons/Makefile.am: use the gdk-pixbuf-csource found at
	configure time if CROSS_COMPILING is set, use the one which was
	just built otherwise.
