I actually read that email, but was on vacation at the time, so it went
right out of my mind -- those pesky holidays and vacations getting in
the way yet again! :,)

I have reviewed your patch.  IMO, only some of it would be accepted into
the mainline source by the PostgreSQL development team.  However, I feel
that your work is important and a very good start.

Would you be willing to take this to the next level?  First, you would
need to make a new Mingw Makefile (src/makefiles/Makefile.mingw) and port
header file template (src/include/port/mingw.h).  Then, diddle with the
autoconf stuff to select these new templates.  Finally, you would need
to convince make to just build the Mingw build-able stuff.

BTW, when reviewing your patch, I noticed a hunk against config.h.  Did
you configure under Cygwin first and then make your changes?  If not,
how was config.h generated?

I would be willing to review your patches before you submit then to
