You didn't provide enough details, but I think I can make reasonable
assumption.

First of all "what" function belong to Math_E_wrapper class

struct Math_E_wrapper : Math::Math_E, boost::python::wrapper<Math::Math_E>

Am I right?

If so, than the line "return Math::Math_E::what(  ); " should be interpreted
by compiler
as a call to base class member function. I think can fix the error by
changing generated
code to be "return this->Math::Math_E::what(  );"

Can you test it?

Take a look on tutorials(
http://www.boost.org/libs/python/doc/tutorial/doc/html/python/exposing.html#python.virtual_functions_with_default_implementations)
The generated code is not that different.

I don't understand the question, can you explain what do you mean?

P.S. If it is possible than switch to MSVC 7.1 compiler. It is much better.
