POSIX is one of those standards that don't really define anything at all. Microsoft POSIX subsystem is one of the nicest examples of something that lets you tick the POSIX checkbox but does almost nothing. One of the recent posix annoyances I stumbled upon was the clock_gettime where every platform has slightly different idea how the different CLOCKs are supposed to be interpreted :) Personally I don't find the APE part of cosmopolitan that interesting, but their own POSIX API <https://justine.lol/cosmopolitan/functions.html https://justine.lol/cosmopolitan/functions.html> which also covers windows is interesting for sure. Zig's std also offers something similar, but perhaps not as good coverage. Getting fork, mmap, and poll work on windows is not small feat.
