I use chibicc to generate the documentation for cosmopolitan. https://github.com/jart/cosmopolitan/blob/master/third_party... I added many of the GNU extensions too, including an assembler. https://github.com/jart/cosmopolitan/blob/master/third_party... Needless to say, I've already ported it to OpenBSD. I ported it to NetBSD, FreeBSD, Windows, and Mac too.

That looks like a very useful C library, thanks for the hint; as it seems it is much more than just a standard C library in that there are also threads, unicode and a lot (all?) of posix features; I do not have the full grasp yet, but it seems that I could use it as a runtime library for my Oberon+ language (which has a built-in FFI and can also transpile to C).
