I would not do anything that was driven by
being usable by the Fortran Tools. That just
does not cover enough of your potential users.
Having said that, I would think that anything
that builds and runs in a Mingw-only
environment should work. I don't think I have
had any problem incorporating into the FT
any binary distribution that is built for
Windows.
Alan: do you really want to look at the results
of my build attempts? It seems quite obvious that
there is something "wrong" with my system
configuration or the way I am trying to do things.
