Well, if you're actively soliciting bikeshedding, here goes: Since we're about to have several -fdefault-real-N flags, would it make sense to instead make a single flag -fdefault-real=SOMEVALUE (and for backwards compatibility, make -fdefault-real-8 an alias for -fdefault-real=8)? And similarly for -fdefault-double=. And since the standard requires that double precision variables are twice as big as reals, in the absence of an explicit -fdefault-double= flag, would it make sense to have -fdefault-real=N imply -fdefault-double=[2*N or if that isn't supported on the target, the largest supported real kind]? (This is sort-of an extension of the current -fdefault-real-8 behavior) -- Janne Blomqvist
