 * All sources must include config.h on the first line to ensure that
 * Large File Support is configured properly.  This header checks
 * whether this has happened.
 *
 * Usage: include this header before you use any of the above types.
 * It will stop the compiler if something went wrong.
 *
 * This is Linux/glibc specific, and only enabled in the debug build,
 * so bugs in this headers don't affect users with production builds.
