+Subject: [PATCH] Fix implicit int warnings
+
+Newer compilers flag this warning which results in configure tests
+failing especially seen on native builds where AC_TRY_RUN is
+being used to detect mutex support.
+
+Also see
+https://sources.debian.org/src/db5.3/5.3.28%2Bdfsg2-11/debian/patches/014-implicit-int.patch
