These have the same meaning as C4996[1] (which we already suppress),
but are triggered by a different mechanism[2].  It makes no sense to
suppress one, but not both.

Of course it would be better not to suppress either, but wrt the two
C4995 warnings we see in php-src, that requires deprecation of using
the ODBC cursor library[3], so might take a while.
