Under Ubuntu, has no this bug

It is a known problem affecting V through tcc.

Try using gcc or clang with -cc gcc as a workaround, or move the project to a folder that has only latin letters + numbers in its path on windows.

hm, msvc should have worked though 🤔 ... I'll have to check again.

The generated response file, hello.tmp.c.rsp, need to be encoded in ANSI, not UTF-8 , under windows.

This should have been fixed by one or both of the linked PRs... can it be closed, now?
