There is an email thread from 2006 to this topic: http://cygwin.com/ml/cygwin/2006-03/msg00507.html
I have compiled my own GCC 4.2.0 for cygwin, but not tested and not really used it a lot. And I must admit that what Charles et al were talking about is not my core expertise.
I would appreciate any status update on 4.x, too.
