Yes, with Cygwin.

Ok, that's what I guessed.

Okay.

Above I have been using FSF sources from gcc.gnu.org patched with the MinGW 
patches from mingw.org.  This works for 3.3.1 but not for 3.3.3.

I will try using the components provided from mingw.org for 3.3.3 as well as
the pristine FSF sources.

I work with C: only.

A couple of other issues:

When I take the FSF 3.3 sources and patch them with Danny Smith's 3.3 patch 
(sent
to a mailing list but never available from mingw.org), the bootstrap fails with
some message about stdio.h.  I remember fixing this somehow (certainly I did,
since I'm using a 3.3 I built myself right now), but I can't recall how.

I tried searching mailing list archives for this issue, since I recall it 
affecting
other people, but couldn't find anything. And this was only in May. Argh.

This wouldn't matter in the first place since I can build 3.3.1, except that 
3.3.1's
libstdc++.a is ten times the size of 3.3's!  That's approximately 9 MB versus 
900 KB.
