Patch looks good, please commit.

You're right, we do. What do you suggest? GCC has a class of
extension warnings that are emitted by default. Is this what you
mean? That would give us:
2. Warning always (eventually enabled or disabled by other -W options)
3. Extension, defaults to a warning
4. Extension, defaults to silent
-pedantic would then map #4 to a warning. -pedantic-errors would
make #3/#4 to error.
