 * by enabling a single header file to embody all knowledge of the names
 * in question.
 *
 * Exactly one module of any executable should #define DEFINE_GLOBALS
 * before #including the header files which use this convention.  The
 * names in question will be defined and initialized in that module,
 * and declared as extern in all other modules which #include those
