 I meant:
 
 - - we need a compiler which generates temporary code at a level between
 assembler/machinecode and C + libc like Forth does. At this level we had
 basic functions, which 
 
 first:
 - - can be compiled/assembled automatically by a stupid Compiler/assembler,
 so we have first the issue of functionality
 
 second:
 - - can be assembled/substituted by handoptimized SIMD-assembler, so we have
 then the issue of higher speed

>>>If you write it it would be nice. But SIMD performance are related to the 
data structure. C are very poor in that domain. That's why we need vectorising 
compiler code ala SSE vector compiler from intel. C is too poor in semantic to 
easly introcuice such powerfull fonction. Or we can simply rewrite C or C++ 
librairy for the Fcpu (STL, Boost, libc). It could be easier but if we have a 
true vector compilier all old C code could be reused without rework.
