+Subject: [PATCH v2] src/log.c: Include libgen.h for basename API
+
+Use POSIX version of basename. This comes to front with latest musl
+which dropped the declaration from string.h [1] it fails to build with
+clang-17+ because it treats implicit function declaration as error.
+
+Fix it by applying the basename on a copy of string since posix version
+may modify the input string.
