This seems to be a good compromise.

What do you mean with 'properly'? For the C backend you can call "ant 
gen-c-native-skeletons" which will generate default implementations of 
native methods in xmlvm/src/xmlvm2c/lib/native. The ObjC backend does 
not have this feature.

No problems at all. ObjC is a superset of C. Just use the .m suffix for 
the filename and you can freely mix ObjC and C. Note that we already do 
this extensively for the Cocoa Touch wrappers 
(xmlvm/src/xmlvm2c/compat-lib/iphone).
