That is already the case.
The issue here is that C23 removed support for the original pre-ANSI k&r style function declarations/definitions and `int func()` was made from meaning an old k&r style declaration to being equivalent to `int func(void)` same as C++.

The idea in musl, is that they declare it using k&r style in `string.h` so that it would be available for glibc compatibility while not breaking applications that re-declare `basename()`, while having the proper definition in `libgen.h`
