Can you send us a small test case?

Yes it won't link. Can you find out what c++filt thinks of the two
mangled symbols?

Not that I know. The symbols (hence the object) would have to be
regenerated from source using updated compilers. Both gcj and g++ from
the trunk and the branch are in sync with respect to the new mangling,
minus bugs that might exist in both implementation but most likely in
gcj since it's the newer of both implementations (but this only a test
case would tell us.)
