     89  *    DETAILED DESCRIPTION
     90  *	This is a Phase I test for the pathconf(2) system call.  It is intended
     91  *	to provide a limited exposure of the system call, for now.  It
     92  *	should/will be extended when full functional tests are written for
     93  *	pathconf(2).
     94  *
     95  *	Setup:
     96  *	  Setup signal handling.
     97  *	  Pause for SIGUSR1 if option specified.
     98  *
     99  *	Test:
    100  *	 Loop if the proper options are given.
    101  *	  Execute system call
    102  *	  Check return code, if system call failed (return=-1)
    103  *		Log the errno and Issue a FAIL message.
    104  *	  Otherwise, Issue a PASS message.
    105  *
    106  *	Cleanup:
    107  *	  Print errno log and/or timing stats if options given
    108  *
