Postgresql under cygwin just stopped working.

Hello List,

I have been using PostgreSQL under CygWin for some time now and have been
very glad, but this day it just stopped working. I can't see what the
problem is, but 3 things has happend since yesterday where is ran fine:
1. I installed CygWin/X
2. My my laptop did'nt wake up after hypernate so I had to turn it off
3. I have just installed the Windows XP service upgrade

I was using the IPC daemon2 as an NT service, but I have also tryed using
the cygserver.

When I try to start this happens:

$postmaster -D /var/postgres/data/
Bad system call

and with debug level 5:

$ postmaster -d 5 -D /var/postgres/data/

I tryed reinstalling the postgresql packages (7.3.1) from cygwin, but I
have not ran a initdb yet. Any idea's?
I would be very glad for any reply that could help solving this. Thanks.

Regards,
Martin
