1547 * 1 = supports declaration of void
1548 * 2 = supports arrays of pointers to functions returning void
1549 * 4 = supports comparisons between pointers to void functions and
1550 * addresses of void functions
1551 * 8 = suports declaration of generic void pointers
1553 * The package designer should define VOIDUSED to indicate the requirements
1554 * of the package. This can be done either by #defining VOIDUSED before
1555 * including config.h, or by defining defvoidused in Myinit.U. If the
1556 * latter approach is taken, only those flags will be tested. If the
1557 * level of void support necessary is not present, defines void to int.
