)1) The fact that access does not provide an option to test the effective uid
)   is brain damage.

And the following piece of kernel code:

	/*
	 * If you're the super-user,
	 * you always get access.
	 */
	if (u.u_uid == 0)
		return (0);

)2) It only matters if the program calling access has S_ISUID or S_ISGID set.

Not true.

)   Why would test be installed with set-uid privileges?

What if the program (e.g. the shell) that _calls_ `test', is setuid?
(I.e. its effective uid differs from its real uid.)
