Comment 6 misinterprets the standard in multiple ways :)

Narrowing conversions do require a diagnostic, but a warning *is* a diagnostic,
so G++ is compliant in this regard, this is not a GNU extension.

Whether the diagnostic should default to a warning or an error or a "pedwarn"
(the category of diagnostic enabled by -pedantic and made into errors by
-pedantic-errors) is debatable, but the current behaviour is the result of a
conscious decision and is not a bug (certainly not Severity=major)
