3866         version of a relaxable macro is needed.  Return -RELAX_SECOND if the

3869         (md_convert_frag): Go through the fixups for a relaxable macro and
3870         mark those that belong to the unneeded alternative as done.  If the
3871         second alternative is needed, adjust the fixup addresses to account
3872         for the deleted first alternative.
