G77 warnings as errors

[Phil Klunzinger <phil at wavefun dot com>]

All warnings in my fortran code stop compilation with an error code.
The obvious work around (other than writing cleaner code) is to run
with warnings turned off (-w or -W...) but i like to see the warnings.

[I tried to submit this as a GNAT but for some reason that failed.
  I hope this is the correct place for this.]

For example, on my machine: "g77 -c foo.f" will fail, not just spew
out the appropriate warning.

-- begin foo.f --
         subroutine foo(N,A,ii)
         integer N,ii(N),iptr
         real*8 A(N)

         call c_bzero(ii,N*4)
         call c_bzero(A ,N*8)
         iptr = memDgrab(N*N)
         call c_bzero(%val(iptr), N*N*8)

         return
         end
--- end foo.f ---

apologies for the obvious bad code.  This is just an example.
