Thanks, but...  are you sure you created this with the test DLL I sent
you the URL for?  The attached strace looks like stock Cygwin.  It
doesn't contain any of the additional strace output the DLL is supposed
to generate and some of it is in a code path you can't avoid when
calling functions on files.

I'll upload a new DLL to the URL I mentioned in PM in a minute, just to
be sure I didn't screw this up myself.


Thanks,
Corinna
