FWIW, AFAIK cgf uses a cross-compiler to build mostly everything he builds 
for the Cygwin distri (but cgf, please correct me if I'm wrong and/or 
you've changed your habits).

There is a small patch to be applied to vanilla gcc to have it be 
compatible with Cygwin's gcc (double alignment in structures). There's 
been a discussion on that only last month. Because of this (and other) 
reason(s), you really should use Cygwin CVS to build this.

cgf posted minimalist instructions recently (Jan or Feb, I don't recall - 
but you can search the ml archives for it) that tells you how to do it, 
with an explicit warning that he wasn't going to help out on it.
