/***********************************************************************
**  1996 - Netscape Communications Corporation
**
** Name: attach.c
**
** Description: Platform-specific code to create a native thread. The native thread will
**                            repeatedly call PR_AttachThread and PR_DetachThread. The
**                            primordial thread waits for this new thread to finish.
**
** Modification History:
** 13-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.
** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
**			recognize the return code from tha main program.
** 12-June-97 Revert to return code 0 and 1.
