The Fastest Mutexes
Case in point:
https://github.com/jart/cosmopolitan/blob/master/libc/sysv/s...
The system call numbers of all the unixlikes are bitwise packed into a single number. There is exactly one of those columns which is stable: the Linux one. Everything else is not part of the binary interface of their respective operating systems.
I've written about how Linux is special in this regard:
https://www.matheusmoreira.com/articles/linux-system-calls
It's a neat hack but I'm afraid it's in grave danger of falling victim to the Darth Vader of OS ABI stability.

Cosmopolitan Libc makes C a build-once run-anywhere language, like Java, except it doesn't need an interpreter or virtual machine. Instead, it reconfigures stock GCC and Clang to output a POSIX-approved polyglot format that runs natively on Linux + Mac + Windows + FreeBSD + OpenBSD + NetBSD + BIOS with the best possible performance and the tiniest footprint imaginable. - Cosmopolitan 3.6.1

Pnut: A C to POSIX Shell Compiler you can Trust
My comment was based on cloning master yesterday and trying to build redbean but hitting what looks like https://github.com/jart/cosmopolitan/issues/940
Indeed it lioks like the commit you mentioned should have fixed the issue with the pointer having too many bits for the weird kernel used on android and some raspis. Fingers crossed that release works.
