Since I'm a Postgres committer (and the only one interested in Cygwin at all) I'm in a good position to do this.

However, that surely need not stop us from getting this working. cheers andrew -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
