Would be a lot better if it came with tests. Please do this justice and dont let it rot as a gist, make a real repo and add some docs and at least smoke tests or some kind. Thanks

I'm tempted to execute it, but it may as well be shellcode I couldn't tell.

Single standalone file, no external tools used, PATH='' (empty), portable (bash, dash, ksh, zsh), produces x86 ELF executables, has mini-libc builtin.<p>Usage:<p>printf 'int main(){puts("hello");return 0;}' | sh c89cc.sh > hello<p>chmod +x hello<p>./hello

It targets x86-64/ELF? I thought it would target `sh` to be portable?

Many parts of this are clearly autogenerated, but that in no way diminishes the sickening impressiveness of it!
