1555 * This symbol contains a list of signal numbers, in the same order as the
1556 * SIG_NAME list. It is suitable for static array initialization, as in:
1557 * int sig_num[] = { SIG_NUM };
1558 * The signals in the list are separated with commas, and the indices
1559 * within that list and the SIG_NAME list match, so it's easy to compute
1560 * the signal name from a number or vice versa at the price of a small
1561 * dynamic linear lookup.
1562 * Duplicates are allowed, but are moved to the end of the list.
1563 * The signal number corresponding to sig_name[i] is sig_number[i].
1564 * if (i < NSIG) then sig_number[i] == i.
1565 * The last element is 0, corresponding to the 0 at the end of
1566 * the sig_name list.

1596 * This symbol indicates how much support of the void type is given by this
1597 * compiler. What various bits mean:
1599 * 1 = supports declaration of void
1600 * 2 = supports arrays of pointers to functions returning void
1601 * 4 = supports comparisons between pointers to void functions and
1602 * addresses of void functions
1603 * 8 = suports declaration of generic void pointers
1605 * The package designer should define VOIDUSED to indicate the requirements
1606 * of the package. This can be done either by #defining VOIDUSED before
1607 * including config.h, or by defining defvoidused in Myinit.U. If the
1608 * latter approach is taken, only those flags will be tested. If the
1609 * level of void support necessary is not present, defines void to int.
