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. :)

Thanks,
Ernesto
