[boost] [python] type attributes in forward declarations

Class declarations like this...

        class BOOST_PYTHON_DECL wrapper_base;

are causing compiler warnings on gcc 4.0.2 with a warning like:

        type attributes are honored only at type definition

However, I see this is also used to handle the insane import/export
windows DLL stuff.  Since I do not do much compilation on the windows
platforms anymore, is the BOOST_PYTHON_DECL really necessary in the
forward declaration, or is it just a convention?

Thanks!
