Not quite regular.  It has $'s in identifiers (presumably because it's
C++ trying to represent Java identifiers), which is what the error
message is telling you.   It could be that gcc is trying to avoid
passing $'s to the assembler on this architecture.  See e.g.
http://gcc.gnu.org/ml/gcc/1999-01n/msg00027.html
which mentions a config setting NO_DOLLAR_IN_LABEL

I don't know what the real story is.   Best ask on the gcj mailing list.
