It's not true in ANY version of UNIX, System V *or* 4.3BSD.  In BOTH
versions, if you set "opterr" to *zero*, it will suppress the error messages.
Read the code, not the manual page!  The S5 page lies because it says
setting "opterr" to a non-zero value turns off error messages; the 4.3 page
doesn't indicate that setting "opterr" to zero turns off error messages.
