Many thanks for the new gcc-mingw update! Everything works (as far as I
tested) now.

Yes, you must use a MinGW version of libg2c.a.

g77 -mno-cygwin

[Simon Cooke]

I tried to use g77 from the latest net release (GNU Fortran 0.5.25 19991024)
with the -mno-cygwin flag, and a trivial example fails to compile:

      program testg77
      end

gives

$ g77 -mno-cygwin testg77.f

A similar problem with gcc was reported in the mailing list

  http://sources.redhat.com/ml/cygwin/2000-05/msg00834.html

and reportedly fixed

  http://sources.redhat.com/ml/cygwin/2000-06/msg00938.html

Must I use a mingw32 version of libg2c.a, or would a similar fix be possible
for g77?

Thanks for any help,
Simon
