Right, makes sense since you didn't also include the runtime DLL.

Well, most things are possible if you have the right knowledge/try
hard enough.  :-)  That said, it certainly isn't set up to be possible
and I've never done it or heard of anyone doing it.

The same issues as if you were able to statically link the code into
your DLL.  Namely, your code would have to be GPL'd.  So you'd have to
be willing to ship sources for your application and Cygwin32 on
demand.

Cygnus sells a commercial license that doesn't require shipping
sources for either the application linked against it or the DLL.  This
comes with support contracts for the native Win32 compiler.  You
may want to contact info@cygnus.com about this option if you're
interested.

Alternatively, if you aren't trying to port Unix code to Win32, try
the Mingw32 configuration.  (See the Cygwin32 web site for details).
That way, you could avoid the GPL issue but that'll only work if your
app is a native Windows application...

You're most welcome!
