Which operating system versions are supported? about cosmopolitan HOT 1 CLOSED

My intended support vector has been the following:

• Red Hat 5+ circa 2007 since (1) it's required by manylinux1, (2) it isn't eol yet, (3) it's the last linux with sysv init, and (4) it's the last GPLv2 licensed Linux. I also view Red Hat releases are epochs for all distros, so that includes Debian 4+ and all the other great distros like Alpine, etc. See syscalls.sh for more details.
• Windows Vista+ since that's the first 64-bit one.
• Mac OS X latest and greatest
• FreeBSD latest and greatest
• OpenBSD 6.4 since they may have recently added restrictions that forbid static binaries
• DOS is same as BIOS in theory but haven't tried it lool see https://github.com/jart/cosmopolitan/blob/master/ape/ape.S

It sounds like, based on what you're telling me, I've exceeded my own goals! Thanks for independently testing and reporting this information. It's super helpful. I'm reluctant however to make official promises in a more visible place like the README. This is a scrappy project operating on a budget, aiming to do more with less, so any promise we do make, we want to be certain we can keep it!
