+Subject: [PATCH] mraa: Use posix basename
+
+Musl has removed the declaration from string.h [1] which exposes the
+problem especially with clang-17+ compiler where implicit function
+declaration is flagged as error. Use posix basename and make a copy of
+string to operate on to emulate GNU basename behaviour.
