- *    DETAILED DESCRIPTION
- *	This is a Phase I test for the setgroups(2) system call.  It is intended

- *	should/will be extended when full functional tests are written for
- *	setgroups(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

Also after this change the ngrps is no loger set and we pass 0 as the
number of groups to the setgroups call.

Since you are using the guarded buffers these two has to be just
pointers, i.e.

static GID_T *groups_get;

There is no point in passing the value via variable, we can as well pass
1 directly to the getgroups/setgroups calls.

We have to clear the groups_get[0] here as well, in the case that we are
looping with the -i parameter, i.e.

	groups_get[0] = 0;
