Thank you. It really wasn't that hard to decipher once I knew where
to look. :)
It currently has
%{mcpu=403: -mppc} \
and should be changed to
%{mcpu=403: -m403} \
%{mcpu=405: -m405} \
Right?
Also gcc does not appear to know anything about the -m74xx set of
switches. Should it? I know RTEMS uses inline assembly that
makes this matter sometimes.
