Disable the warning about the case when a conversion function converts an
object to the same type, to a base class of that type, or to void; such
a conversion function will never be called.

+Warn about deprecated uses of the volatile qualifier. This includes postfix

+using simple assignments where the left operand is a volatile-qualified
+non-class type for their value, compound assignments where the left operand
+is a volatile-qualified non-class type, volatile-qualified function return
+type, volatile-qualified parameter type, and structured bindings of a
+volatile-qualified type. This usage was deprecated in C++20.
Just a minor thing: Since the text uses volatile as a keyword
(as opposed to an adjective) it should be @code{volatile},
analogously how it's quoted in warnings.
