+       Some POSIX feature test adjustments.
+
+       * include/stdlib.h (mkstemp): Available since SUSv3, so requires...
+       [_POSIX_C_SOURCE >= 200112L]: ...this minimum level of POSIX support.
+       (mkdtemp): This didn't become available until SUSv4, so requires...
+       [_POSIX_C_SOURCE >= 200809L]: ...this increased feature level.
