2 * teststrtoul.c --
3 *
4 * This file contains a simple program to detect broken versions
5 * of strtoul, like those on AIX. The broken versions return an
6 * incorrect terminator pointer for the string "0". This program
7 * exits with a normal status if strtoul does the right thing, and
8 * it exits with a non-zero status if strtoul is bogus. Unlike
9 * the other test programs, this one must actually be executed to
10 * be sure that it works.
