+Subject: Support POSIX basename() from musl libc
+
+Musl libc 1.2.5 removed the definition of the basename() function from
+string.h and only provides it in libgen.h as the POSIX standard
+defines it.
+
+This change fixes compilation with musl libc 1.2.5.

+
+basename() modifies the input string, copy it first with strdup(), If
+strdup() returns NULL the code will handle it.
