2822 * 4 = supports comparisons between pointers to void functions and

2824 * 8 = suports declaration of generic void pointers
2825 *
2826 * The package designer should define VOIDUSED to indicate the requirements
2827 * of the package. This can be done either by #defining VOIDUSED before
2828 * including config.h, or by defining defvoidused in Myinit.U. If the
2829 * latter approach is taken, only those flags will be tested. If the
2830 * level of void support necessary is not present, defines void to int.
