Glad that it was easier to fix than expected. The 'e' program (see previous e-mail)
is OK now (since a is not a square).
% ./e
a=13017918183496977133775209079164003070786863049686786465873731362497345253379866083852810820103005813030391929785402872601518953148250859762321945896609724349178326747526622443454716367524

Also OK is now the mpc-1.0.0rc1 testsuite for the powerpc-apple-darwin9.8.0 architecture.
Thank you for your time,
