  <koff>  Haven't seen any other reports of this?  You're the second person
to post about it this week!  Take a look at this line from

  You need to work on your websearching skills!

  Hell, some of those are a bit old.  Let's tighten it up a bit by only
searching this year's archives:

  It is apparently fixed in later versions of the cygwin w32api package.
Check the following posts for details and a suggested fix that works around
it by killing the dllimport attribute:

You'll also need to use this patch:

http://sources.redhat.com/ml/insight/2004-q2/msg00032.html

and take account of these facts:
