I'd like to avoid any sort of copying or linking. 

After fooling around with this, I think the best way to do
this is to have 

 gdkwindow.c
 beos/gdkwindow.cc

Then have beos/Makefile.am build a libtool convenience 
library of the .cc files under beos and link that into
libgtk.la which is created in the main gdk/ directory.

I've tried this with a little sample setup and it seems
to work OK.

Does this sound reasonable?
