Running glib, gtk+ 2, etc. on cygwin

Has anyone gotten the gtk+ 2 stuff to compile under cygwin?  I want these 
to compile under cygwin natively, i.e. I want them to run within cygwin. 
This would be different than Tor's stuff, since he's just using the cygwin 
environment to compile them for Windows. 

I'm asking because I'd like to compile some GTK apps under cygwin for use 
within the cygwin X environment.

I've downloaded the source for glib 2.0.7 to start with and although the 
configure seems to run fine, the make fails saying it can't find 
definitions for some g_ functions.  I'm guessing that it's not finding the 
headers in the right spots or something.  I haven't put much time into 
this so it might be an easy fix.

Thanks
Bill
