--- Comment #14 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-03-16 10:00:38 UTC ---
To be clear: the way the thing is supposed to work, **only** basic_string
should be special, because **only** the extern template for basic_string are
guarded by "#if _GLIBCXX_EXTERN_TEMPLATE > 0" instead of "#if
_GLIBCXX_EXTERN_TEMPLATE". If something special is happening elsewhere then
it's an unintended bug.

Now, if something got broken lately, like those sed, I have no idea, certainly
I didn't change that. But, please post and discuss the issue and tentative
fixes on the libstdc++ mailing list, not here.

Benjamin, any idea about those sed?
