** Name: depend.c
** Description: Test to enumerate the dependencies
*
** Modification History:
** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
** The debug mode will print all of the printfs associated with this
*test.
** The regress mode will be the default mode. Since the regress tool
*limits
** the output to a one line status:PASS or FAIL,all of the printf
*statements
** have been handled with an if (debug_mode) statement.
