Cool. I'm going to try it.

This is what I intended.  I currently have a mingw32 target gcc 2.8.1
hosted
on solaris.  It was a real trial getting stl working.  I think I finally
just copied some of your files down and it just worked!  It's been a
while,
(early fall of last year?) and I haven't used it much because of the
above
questions.  I'm going to play around some more though.

Thanks!
