Er, OK. This means I can't patch it without conflict.
Mind just adding the six lines of code needed for
support of regparm(3) apps?

No. I'd thought that the two cases should match.
The regparm(3) case should remap signals if and only if
the regparm(0) case remaps signals. Perhaps this
is not correct if the remapping is not needed for
native Linux apps; I doubt iBCS stuff would ever be
needing regparm(3) support.

Since you plan to delete the remapping cruft from
the regparm(0) case, then obviously it should not
be added to the regparm(3) case.
