When Stu did this, there was no mention of Java in the still-drafty
Dwarf 2 spec. What's in GCC includes Dwarf 2.1 draft, so it's more
recent, but beware of many inconsistencies. (diff of gcc/dwarf2.h
and include/elf/dwarf2.h is positively scary, since they're supposed
to be identical)

Will GDB need to be able to recognize the old language code, perhaps
in an old piece of gcj output? You could leave the old code in
dwarf2.h, just give it a different symbolic name.
