--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Yes I noticed this recently, and plan to change it.

For the char and wchar_t specializatiosn it looks like we simply never changed
them to match the C++11 change. The char16_t and char32_t specializations that
were added in C++11 should have been added with the new signatures, since they
never existed in the old form.
