Does anyone have a working sample with enums, 'cause this code below gives an compile error with MSVC6 SP5

----------- code snipped below

enum KEY
{
TAB    =8,
CR    =10,
ESCAPE   =27,
SPACE   =32,
};

boost::python::enum_as_int_converters<KEY> thekeys;

this_module.add(boost::python::to_python(TAB), "TAB");

--------------- compile error message
