Mark,

Rebasing all of your Cygwin DLL's *should* fix this. If you don't have the
rebase package installed install it via setup.exe and follow this (taken
from the rebase README):

Use the following procedure to rebase your entire system:

    1. shutdown all Cygwin processes
    2. start bash (do not use rxvt)
    3. execute rebaseall (in the bash window)

Once you've follwed these steps things should work.
