Bug in GCC / libstdc++: Space character categorized as non-printable by std::ctype

In C++, a space character is reported as non-printable by `std::ctype` in the "C" locale (the only locale supported by `std::ctype`). In other words, the following expression evaluates to `false`: ctype.is(std::ctype_base::print, ctype.widen(' ')) where `ctype` is obtained by `std::use_facet>
