I'd like to be able to set my default CFLAGS to include
	-ffast-math, but there are certain packages where this
	would be a Bad Thing (postgresql comes to mind).

	Would anyone object to me adding another pkgsrc variable
	set that can be used to indicate where packages must not
	be optimised in a certain way (that can then be tested
	in mk.conf).

	Maybe OPTIMISE_EXCLUDE_FAST_MATH=yes ?
