Build error using clang 17 on musl (call to undeclared function 'basename')

Hello! Musl has removed the declaration of basename from string.h, which now causes a build error when using clang 17+ on musl. https://git.musl-libc.org/cgit/musl/commit/?id=725e17ed6dff4d0cd22487bb64470881e86a92e7

A possible solution would be to include libgen.h in the afflicting .c files to use the posix implementation of basename. I do not know if there is a better solution to fix the issue.
