Apple has an Altivec patch for egcs-1.1 derived from work
originally developed by Motorola. Hopefully this patch will be integrated
into the public sources eventually. I have not seen the patch myself, so
I am not sure how much it utilizes Altivec support directly versus
giving the programmer access to the Altivec functionality for use in
Altivec-specific subroutines (BLAS, etc.).
