Nice! Do you foresee any problems with using this behind a transpiled language like Nim?

I haven't used Nim much, but I remember a repo on Github had setup a build script for compiling Nim with Cosmopolitan Libc. https://github.com/Yardanico/cosmonim

This gcc patch makes such build scripts simpler, because you will need to change less of your code -- let me know how it works!
