Change 103927 by jb at jb_freebsd2 on 2006/08/15 00:46:51

	Add a toggle to tell gcc to just STFU when it comes to "#pragma ident"
	that is used EVERYWHERE in OpenSolaris code.
	
	I want to be anble to warn up WARNS to have genuine warnings
	reported, but #pragma ident is just annoying, so just make it
	go away.
	
	This will allow me to undo a lot of the hacks that I've had to do
	to OpenSolaris files.
