huge(0): 2147483647 ! biggest (positive) number fitting into integer(4)
Z'FFFFFFFF': 4294967295
I would argue that 4294967295 is bigger than 2147483647. If one allows the
overflow or regards it as bit pattern, one obtains "-1". This is also what one
gets for -fno-range-check.
The program is simply invalid though as vendor extension many compilers allow
it. One can discuss about the default behaviour in gfortran [write to the
mailing list and not here], but the current behaviour has some merits, though I
think one should point to the option which allows the compilation (see patch in
comment #2).

This was fixed meanwhile. gfortran 4.3 does not have this error any more.
4.3 binaries are available at: http://gcc.gnu.org/wiki/GFortranBinaries
