michael@0: ** Name:		depend.c
michael@0: ** Description: Test to enumerate the dependencies
michael@0: *
michael@0: ** Modification History:
michael@0: ** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
michael@0: **	         The debug mode will print all of the printfs associated with this test.
michael@0: **			 The regress mode will be the default mode. Since the regress tool limits
michael@0: **           the output to a one line status:PASS or FAIL,all of the printf statements
michael@0: **			 have been handled with an if (debug_mode) statement.
