Description Anders F Bj 2006-05-09 10:52:01 UTC 
The AltiVec blitters don't compile, since they require __VEC__ to be enabled in order for the compiler to understand "vector" and friends (i.e. do AltiVec)
But you don't want to turn AltiVec on globally, since then the code would only run on a G4 (there are already runtime tests, before using the AltiVec variants)

The solution here is to enable AltiVec locally, for the actual AltiVec code.
