--- Comment #7 from Bill Schmidt <wschmidt at linux.vnet.ibm.com> ---
Chandler privately reported an issue with this again recently.  After
discussing with David Edelsohn and going through some of the gcc history, it is
certainly true that -faltivec should include altivec.h automatically, but
-maltivec should not.  So the way this was resolved previously would appear to
be wrong.

I will look into the issue this week.  I expect we will have a lot of test case
fallout to get this to work as it was originally intended.
