	* gconf/gconfmm/setinterface.h: Use 
	#pragma GCC system_header
	to supress warnings about the lack of a virtual destructor.
	We cannot add the virtual destructor (not a big problem in this 
	case anyway) without breaking ABI, and we do not want to stop 
	applications from building while -Werror is enabled.
	Bug #460969

        * scripts/macros.m4: Check for both m4 and M4 in the GNU m4 output,
        to fix the build on some platforms.
        Bug #423990
