-/* VOIDFLAGS:
- *     This symbol indicates how much support of the void type is given by this
- *     compiler.  What various bits mean:
- *
- *         1 = supports declaration of void
- *         2 = supports arrays of pointers to functions returning void
- *         4 = supports comparisons between pointers to void functions and
- *                 addresses of void functions
- *         8 = supports declaration of generic void pointers
- *
- *     The package designer should define VOIDUSED to indicate the requirements
- *     of the package.  This can be done either by #defining VOIDUSED before
- *     including config.h, or by defining defvoidused in Myinit.U.  If the
- *     latter approach is taken, only those flags will be tested.  If the
- *     level of void support necessary is not present, defines void to int.
