Cases where something about the code is not defined by the base standard,
but a diagnostic is not required. -pedantic may give a warning for such
cases. -pedantic-errors may give an error *if* there is compile-time
undefined behavior (not if the not-definedness is something other than
undefined behavior, or is undefined behavior only if the code in question
is executed, although it will still give a warning for such cases if
-pedantic does).
