How is your compiler configured?
Altivec instructions shouldn't be supported by default, since they are
not supported on all PowerPC chips. You can use -maltivec to turn on
Altivec support, or you can use a toolchain for which the default CPU
includes Altivec support. There may be a bug, of course, but Alan's
specific change appears clearly correct.
