Hello!
I don't want to register as bugzilla for this case so I am using this
interface.
Recently I compiled GNU Emacs 22.0.50 with Apple's gcc 4.0.1 on Mac
OS X 10.4.7 for a PowerPC 7447A processor with particularly these
options:
-faltivec -mcpu=7450 -mpowerpc -mpowerpc-gpopt -mpowerpc-gfxopt
Leaving away -faltivec, gcc complained about optimising for different
CPU subtypes. Keeping it, an executable Emacs was made, but when
launching it without windows it crashed when it had to compute a
square root. In windows mode in X11 when I let Emacs calculate a
square root in Lisp, it crashed, too.
To me it seems as if it is necessary to add a warning about using the
-faltivec switch. It seems it delegates floating point computations
to a library that is not supplied by Apple, but could be part of the
Metrowerks compilers the switch is meant to support.
