Here are some ideas about the Win9x port:
Cygwin runs on Win9x quite well, I think only some security features are
missing. We have made some investigation with pgsql on win95 (with Cygwin
B20.1) and found that the problem is (should be ;-) somewhere in server side
libpq (pg_flush) and here I was stopped due "unsufficient resources" (=
time) ;-). I have tested the SysV IPC functionality and it worked well, so
this should not be the problem.
I will try it with the newest cygwin library and do more debugging.
There are also some new interesting features in the newest cygwin that could
be implemented in the WinNT port (like AF_UNIX sockets)

PS: some money would help ;-)
