I don't think it's a bug, since "the negative number with the largest magnitude
possible within the representation" is not -huge()-1, but -huge().
If I understand the standard correctly, -huge()-1, although being representible
by the hardware you have, is not "within the representation" of this integer
kind, because the range of the representation of an integer kind is supposed to
be symmetric.
For what it's worth, the Intel and Sun compilers have the behaviour you expect,
but the Portland compiler and g95 both have the same behaviour as gfortran.
Steve might have an idea on that, IIRC he's the one who implemented the
-frange-check option. Otherwise, a question to comp.lang.fortran would be a
good thing.
