/* glbl.c - this module holds global defintions and data items.
 * These are shared among the runtime library. Their use should be
 * limited to cases where it is actually needed. The main intension for
 * implementing them was support for the transistion from v2 to v4
 * (with fully modular design), but it turned out that there may also
 * be some other good use cases besides backwards-compatibility.
