	Uh, I do not believe that applies here (Unless different passes of
	the compiler are implemented using the same binary :)

	I understood that a single compile would use cc1, cc1obj and
	(potentially cc1plus), in which case if you are using -pipe then
	you could win with having one copy of in memory shared
	between them?
