I will be very happy to work with you to remove the use of dllwrap etc. 
for cygwin. Since I'm a Postgres committer (and the only one interested 
in Cygwin at all) I'm in a good position to do this. I believe the 
Postgres project had problems in the past with automake and made a 
decision long ago not to use it, so we're not going down that route. 
However, that surely need not stop us from getting this working.

cheers
