[bdavis@localhost bin]$ /usr/local/bin/gfortran --version
GNU Fortran 95 (GCC 3.5-tree-ssa 20040128 (merged 20040102))

Is this legal f90 ? I do not know but it works on f77 compilers.

Confirmed but note that g77 rejects this with -pedantic.

[Bug fortran/13912] [gfortran] Does not accept negative constants

[Tobias dot Schlueter at physik dot uni-muenchen dot de]

It is not valid Fortran, but I vaguely remember that there has been some
discussion on this in the past, possibly in the pre-fork g95 days. It is a
common extension and shouldn't be too hard to implement, though. Of course the
workaround is simple: place parentheses (-1).
