Re: What header is needed "__vector" when using altivec support?

Ernest:

I think you can answer your own question by looking carefully at your  
e-mail and comparing these two statements:

> #include <altivecLib.h>


Perhaps including <altivec.h> instead of <altivecLib.h>  would fix  
your problem? Hope this helps.
