Please add comments here.

According to the GNU Coding standards this should have some more
whitespace, e.g.:
__has_altivec = ((GL (dl_hwcap) & PPC_FEATURE_HAS_ALTIVEC) ? 1 : 0);

Please rewrite your patch to follow the Coding standards everywhere...

This is not a properly formatted comment.

Just one space everywhere.

Missing whitespace again.
