+Subject: [PATCH] Build with -D_DEFAULT_SOURCE along with -std=c11
+
+On its own, -std=c11 hides POSIX and other extensions from C headers
+such as <stdlib.h> when building against glibc.  This causes the
+posix_memalign probe to fail incorrectly with compilers that do not
+accept implicit function declarations.  _DEFAULT_SOURCE is ignored by
+most non-GNU/Linux systems or not relevant in this context, so there
+is no separate check for adding it.
