Function arguments must have first-class types!

Full warning:

Function arguments must have first-class types!
void %0
========== LLVM Verification Failed! ==========

So code like this is invalid and not recommended?

func myfunc(void) int

A lot of C code is written this style, e.g: int main(void). After I removed void the warning disappeared.

Ah yes. func myfunc(void) int is not valid code. func myfunc() int is correct.
