Indeed, if it is the current behaviour, it would be better. I couldn't 
find anything which would enable AltiVec on Darwin, however. The only 
thing I could find was based on cpuinfo, which in turn is based on 
/proc/cpuinfo - and it doesn't exist on Darwin. AFAICT, only an 
explicit --enable-altivec would set $_altivec to true in configure.

I'll try to find out if enabling AltiVec on my G3 will work as it 
should, with runtime detection and all, and report back.
