I agree... though I wouldn't be opposed to both variants... an all-in-one
spell and a split setup... I tend to build atleast gcc,g++,objc and gcj so
having that all-in-one would certainly reduce compile times by a lot.

But in some instances I only want a single one and then add another one
when needed...
