  Finally, I think that this version is wrong...
It fixes linking, but it also
removes the call to add_insns function,
and thus the assembler code is not registered anymore.
This probably kills the functionality of the whole
EMIT_CODE macros.

  Sorry for all those forward/backward steps,
but finally Doug's patch is far better
because it keeps the call to add_insns

  Tom, could you give your approval on
Doug's patch?
