Hi Ben

Look, those functions exist of curse but that is not standard C, those
functions have no links to the rest  of the language.

Besides, they are tied to the Intel architecture (what
is not wrong of course) but the idea behind my post is to try to
abstract a bit from a single architecture to a more *general* SIMD
programming. Note that the notions of container and operations
are NOT tied to Intel, IBM or Motorola vector proposals but could
be used with all three.

Even me with my limited ressources have some intrinsics for some 
operations but that is really not *language* support Ben.
