Typo in subject... frv != MMIX.

(patch not inlined, so I can't quote it as trivially as above.)

Please also change mmix_dbx_register_number to also take its
parameter as an unsigned, or there'd be an odd asymmetry.
(Alternatively, add a comment why that doesn't work.)

Ok with that change.  Thanks!
