You need to either fix the C code or find someone else that can fix it.*
This is code that ensures that function calls correctly match function
definitions using the high tech method of "cross your fingers and hope
that it works".
This was "fixed" by ANSI C going on for 35 years ago. Ancient code like
this is probably safe enough - the finger crossing seems to have worked
for a long time.
It's no wonder people are clamouring to only use safe languages like
Rust for new projects.
