Not that this is germane to the issue you're trying to fix, but:
SOFUN_ADDRESS_MAYBE_MISSING isn't a bug --- it's a feature. Sun made
various adjustments to make fewer stabs require relocation, to reduce
link time. That's why line number stabs are relative to the beginning
of the function, for example. Since every function has a linker
symbol for its entry point, and there are STT_FILE symbols for the
compilation units (I think I've got that right), there's no real need
to put the address in the SO and FUN stabs, too.
