define-struct

[Mike Kestner <mkestner speakeasy net>]

I have cobbled together a struct definition extractor since I was tiring 
of hardcoding struct defs for Gtk#.  It doesn't yet deal with embedded 
unions or structures, but then again, neither does the defs spec. :-) It 
also barfs on non-typedef'd function pointer fields. (/me checks his 
defs spec for function pointers).  There's only one structure that does 
this in the gdk headers though, so perhaps that's an oversite that I can 
clean and try to sneak past the API freeze police.

The script and a set of defs for the gdk structures can be found in mono 
cvs in the codegen directory of the gtk-sharp module. The defs file has 
a few hand edits to work around the union and function pointer things.  

I also have a script that generates signal and property defs from 
source, although I understand those have been handled elsewhere already. 
My props extractor embraces and extends the defs format by adding a 
(doc-string "...") expression to the def. This is so trivial to extract 
that it could probably be added to the spec at this point.
