        * glib/gatomic.c: Non-optimizing compile fails for two asm
        statements on PowerPC. Use generic implementaton for those
        cases. Spotted by Christof Petig <christof@petig-baender.de>,
        fix by Sebastian Wilhelmi. Bug #137006 has a possible alternate
	solution, but we'll be conservative for now.
