I don't do SSE, but you have to enable it before using it (unlike MMX). OpenWatcom's Causeway build supposedly does this now. BTW, if you really want control of your hardware, you're probably going to have to get past the compiler and go to assembly (e.g. FASM supports all documented and undocumented x86-64 instructions for Intel and AMD chips). And yes, you probably knew all this (and more). ;-)

But, like I said, OpenWatcom can output 16-bit code. The potential problem is that it needs a 386+ host. I dunno what this GCC will support (host, target, file format) but it's probably only a cross compiler (386+ host OS like GNU/Linux).
