I'm developing this with Linux, so there's no problem for that (you need
to compile with -march=pentium3). It should also work work for Windows
(now that the inline asm has been removed), but I haven't tested. Of
course, I'd like more testing both on Linux and Windows to make sure I
haven't broken anything.
