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