--- Comment #8 from Vincent Lef=C3=A8vre <vincent-gcc at vinc17 dot net> ---
It is bad that __extension__ does two completely different things:
1. Disable warnings associated with GNU extensions, like ({ ... }).
2. Disable compatibility warnings that do not correspond to GNU extensions,
like invalid conversions in C++.=
