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. For further details, read Cosmopolitan Third Edition, the Cosmo README, and the Cosmopolitan Toolchain README. Prebuilt software is available on https://cosmo.zip/
