Do the only link errors have some reference to
std::__cxx11::basic_string? I don't have access to Windows to verify,
but I think it is correct that these symbols are not in Octave's
liboctave and liboctinterp (at least in Octave 4.0).

Are you building your extension module using the gcc provided with
Octave or using a separate mingw-msys development environment?

If you are not using the gcc provided with the Octave 4.0.0 installer,
which gcc version is it?
