this is wrong

no, I made this file without doing wide bits, so this stuff must have 
been copied by accident.

ok, sounds good. (you could make wide character specializations as in 
the c_io_libio file, if you wanted to implement wchar_t functionality 
with standard wide io functions. That's probably best left for later 
though.)
