I guess that the current CVS reflects your work, right? Anyway, after
working a bit on an IRIX host port, I am quite confident that all
relocations which don't concern variables beginning with "__op_" are
irrelevant, and could be left alone. Those relocations are almost
definitely handled by the linker already.

The file op.o *is* linked into libqemu.a, because there would be no code
to actually be dynamically copied. I will explain the dynamic translation
in an other post very soon.

Ciao,
