    Check out last month's issue of the C/C++ Users Group magazine.
It contained a memcpy() replacement for the pentium that is 15% faster
than any of the current compilers.  Also says that you will be able to
get move 30% faster than memcpy when MMX and Cyrix M2's come out.
But for 486's, and such you just have to optimize! ;-)
