I've seen 64-bit emulation code in FreeBSD about two years ago... And it compiled cleanly with gcc-2.6.x too. It didn't use long long variables but an array of two 32-bit variables and overflow detection. Don't ask about performance... Firstly I never came around to measuring it, and secondly I don't remember the exact structure of the code any more :-)
Too bad I lost that 4G drive with the FreeBSD cd copied onto a spare partition :-(
