Yes, that got it for me. I just did not realize where altivec.h was
hiding. For vxWorks it lives here:
=======================================================================================================
<Install_Dir>/gnu/3.3.2-vxworks-6.2/x86-linux2/lib/gcc-lib/powerpc-wrs-vxworks/3.3.2/include/altivec.h
========================================================================================================
I am in business now. :)
