   It's because your toto.c does not cause gcc to generate AltiVec code,
but it may happen (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=408918).

   I added proper runtime AltiVec detection, as well as a fix for the
makefile so that only ppc/*.c files get compiled with the AltiVec flags,
can you give the current trunk a try?
