Cosmopolitan v4.0.2
Cosmopolitan Libc makes C/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 7.3 + NetBSD + BIOS with the best performance and reliability.
Cosmo v4.0.2 Release Notes
After testing 4.0.x with various programs and hammering out the
remaining issues, this release includes the latest build of Cosmos.
We've confirmed bash, emacs, vim, git, links, wget, etc. work well
across platforms.

Cosmopolitan v3.9.2
Cosmopolitan's Windows support may finally be feature complete. It's now
possible to send signals between processes using kill() on Windows. Ten
new torture test programs have been written to tease out more fixes and
offer a high level of assurance that signal handling is correct. Some of
these tests are good enough to deadlock the signal handling of UNIX OSes
but not our signaling module for Windows. They also demonstrate that our
Windows signal handling actually outperforms many UNIX OSes at latency.
