[Bug c/23267] New: strftime options generate spurious warnings

["cmattair at pdq dot net" <gcc-bugzilla at gcc dot gnu dot org>]

When I specify -Wall, certain strftime options generate spurious warning messages.
Specifically, %D and %y generate the following warnings:
   warning: `%y' yields only last 2 digits of year
   warning: `%D' yields only last 2 digits of year

This is the documented behaviour of these options so the warning seems a little
out of place.  Equivalently, you should warn me that
   warning: sin() does not generate the cosine.

These warnings should be removed or replaced with
   warning: GNU expects you to display four digit years
