native windows f77 compiler

[aldous]

I need a free f77 compiler to run in my native
windows environment so that I can link with
my Borland C++ compiler.

I thought cygwin provided the gnu compiler for
that but after installation I discover I'm running
in a bash shell, more like linux, and not producing
object formats I can link in with windows compiled code.

Actual sites you've downloaded and used that will
accomplish what I wish?
