+From b21a9d4f10a066cac76bb345d31fdd24afcf3e6f Mon Sep 17 00:00:00 2001
+From: Fathi Boudra <fathi.boudra@linaro.org>

+Subject: [PATCH] musl: basename: use portable implementation for basename API
+
+musl has removed the non-prototype declaration of basename from string.h which
+now results in build errors with newer clang compilers.
+
+Implement GNU basename behavior using strchr which is portable across libcs.
+
+Fixes:
+| ../../git/tools/mountcomposefs.c:43:20:
+| error: call to undeclared function 'basename'; ISO C99 and later do not
+| support implicit function declarations [-Wimplicit-function-declaration]
+|    43 |         const char *bin = basename(argv0);
+|       |                           ^
+| ../../git/tools/mountcomposefs.c:43:14:
+| error: incompatible integer to pointer conversion initializing 'const char *'
+| with an expression of type 'int' [-Wint-conversion]
+|    43 |         const char *bin = basename(argv0);
+|       |                     ^     ~~~~~~~~~~~~~~~
