38 * is enlarged in steps of STRBLEN bytes.

49 * Sizes of hash tables
50 * Should be a prime. Possible primes are
51 * 307, 401, 503, 601, 701, 809, 907, 1009, 1103, 1201, 1301, 1409, 1511.
53 * HSHSIZ1 symbol table 1st pass
54 * HSHSIZ2 symbol table 2nd pass
55 * THSHSIZ2 type table 2nd pass
62 * Should be set to 1 if the difference of two pointers is of type long
63 * or the value of sizeof is of type unsigned long.
