mingw (now mingw64) has been doing that for ages as well -- I&#x27;m too busy to check right now, but I suspect since before clang supported windows.<p>gcc has had support for every operating system under the sun at one point or another - I fondly remember using the DJDelorie version for DOS+Extender, and if I&#x27;m not mistaken, there was also a release that could do WIN32 on Windows 95 from delorie.
