 /***********************************************************************
 **  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.
