Yes, the secured API isn't provided in msvcrt's import, as it is not
necessarily part of it. So you need to use msvcr80.dll or higher. We
don't provide the .def files for it at the moment, but you can use the
'gendef' tool to generate such an import library for it (see our crt
Makefile to see how DLL import libraries can be generated by a .def
file).
Regards,
Kai
