24 * All sources must include config.h on the first line to ensure that

28 * Usage: include this header before you use any of the above types.
29 * It will stop the compiler if something went wrong.
30 *
31 * This is Linux/glibc specific, and only enabled in the debug build,
32 * so bugs in this headers don't affect users with production builds.
