My (humble) suggestion would be to start with the compiler builtins, 
rather than by writing assembler.  My understanding is that gcc >= 4.1 
on virtually all platforms and the Intel compiler have compatible sets 
of builtins, and the Microsoft compiler has something equivalent.  I 
don't know about the other Boost-supported compilers - can anyone fill 
in the gaps?  The biggest hole that this would leave is gcc < 4.1; 
what's the policy about ongoing support for older compilers?
