   4 Subject: [PATCH] mraa: Use posix basename
   5
   6 Musl has removed the declaration from string.h [1] which exposes the
   7 problem especially with clang-17+ compiler where implicit function
   8 declaration is flagged as error. Use posix basename and make a copy of
   9 string to operate on to emulate GNU basename behaviour.
