You don't have to, I did it already.. =)

Shortly no. Longer answer is yes it does.

I rember writing a few articles about this...

Basicaly thing goes so that you compile (but not link) needed files, 
generate needed .lib:s and then link whole thing.

Note that you can export symbols from .exe in same way.

Here is few pointers:

<http://mail.gnu.org/archive/html/libtool/2002-10/msg00145.html>

<http://sources.redhat.com/ml/cygwin/2003-12/msg01071.html>


And bad news is: libtool can't handle this (at least not to my knowledge).

Because this is strictly windoze specific, this is also a offtopic of 
this mailinglist..
