That's what I thought, but I saw:

  #ifdef _GLIBCPP_USE_WCHAR_T
    typedef _IO_wide_data __c_wfile_type;
    extern "C" struct __c_libio_codecvt { };
  #endif 

So, I assumed that you must have intended to use libio for the
wide-character bits.

If that can go -- and if we can always make _GLIBCPP_USE_WCHAR_T false
when c_io_stdio is in use, then we can get rid of my change.  If you
approve that direction, I'll make the necessary changes, including the
minor configury bits.
