Perhaps a work-around would be to add an extra stubedit field containing
the base (e.g. default 100) for these return values? This would of course
hamper diagnostic programs which rely on a fixed set of return values, but
perhaps it would be possible for such software to extract this value from
the executable. If such a diagnostic utility was designed to diagnose only
one executable (as is the case with DJVERIFY) then the modified set of
values could be hardcoded anyway.
