  * 	The standard options for system call tests are accepted.

  *      No run-time environmental needs.

  *    SPECIAL PROCEDURAL REQUIREMENTS
  * 	None
  *
  *    INTERCASE DEPENDENCIES
  * 	None
  *
  *    DETAILED DESCRIPTION
  *	This is a Phase I test for the gethostid(2) system call.  It is intended
  *	to provide a limited exposure of the system call, for now.  It
  *	should/will be extended when full functional tests are written for
  *	gethostid(2).
  *
  * 	Setup:
  * 	  Setup signal handling.
  *	  Pause for SIGUSR1 if option specified.
  *
  * 	Test:
  *	 Loop if the proper options are given.
  * 	  Execute system call
  *	  Check return code, if system call failed (return=-1)
  *		Log the errno and Issue a FAIL message.
  *	  Otherwise, Issue a PASS message.
  *
  * 	Cleanup:
  * 	  Print errno log and/or timing stats if options given
  *
  * 	History:
  * 	  12/2002 Paul Larson - Added functional test to compare
  * 	  	output from hostid command and gethostid()
  *
  *        01/2003 Robbie Williamson - Added code to handle
  *              distros that add "0x" to beginning of `hostid`
  *              output.
  *
  *   01/31/2006  Marty Ridgeway - Corrected 64 bit check so
  *              the second 64 bit check doesn't clobber the first 64 bit
  *              check
