Ok here some more information. First of all fetchmail seems to work fine
when NOT running in daemon mode (fetchmail --nodetach).
I build a debugable dll from the 20040122 snapshot and also debugable
versions of fetchmail and procmail. I then followed the instuctions in
winsup/cygwin/how-to-debug-cygwin.txt.
Here are the results from the fetchmail.log file and below the three
console windows which appear as soon as fetchmail starts fetching the
first mail.

I dont know if this is enough information to solve the fetchmail issue.
But if somebody has any ideas how to debug this further please tell me.
