it sounds like the categories are not defined for the Cocoa classes. I'm
assuming that you are linking in all files that are contained in
src/xmlvm2objc/compat-lib/*, correct?
If the code you are compiling is just plain Java code, I would suggest
you use the new C backend. Try --target=posix and have a look at the
code. One benefit is that it pulls in cross-compiled versions of Apache
Harmony, so the J2SE API is much more complete than what we have right
now on the Objective-C side.
