is it a good idea to overwrite GCC_DEFAULT_VERSION= in Mk/bsd.gcc.mk?

	this should work.  In my experience most ports that work with
	GCC 4.6 also should with GCC 4.7, and most have USE_GCC=4.6+
	anyway, so other users may well have built them with a later
	version aleady.

	One or the other port may exhibit a compile problem, in which
	case that would be an excellent opportunity to file a report
	against it and inform its maintainer.

	That's what I have been hoping to do, yes.  With the ports
	build cluster being unavailable for months now, we simply
	could not do the necessary testing though.

	Anyone who wants to give this a try, I'd be happy to see that.

ok, sure, I'll try it on ia64 first.

I'll get back to you
