The following section of the Renaissance manual might apply --

"2.5.2 A small tweak to get it to work on Microsoft Windows

If you are only using the NSBundle Additions API, you can have a  
problem on Microsoft Windows where you need to reference something  
inside a library to get it linked in. The recommended workaround is  
to add the following line (or a similar one) to your program  
(typically in your main.m file):

int (*linkRenaissanceIn)(int, const char **) = GSMarkupApplicationMain;

This defines a (dummy) function pointer called linkRenaissanceInt,  
and generates a reference to GSMarkupApplicationMain which fixes the  
problem."

Let me know if that fixes it. ;-)
