Module Building, and MinGW

thanks for the replys.
got some more questions.

Why can't we include headers, ie .h.
and how do I set an external function that is in a class.

ie

class cNumber
{
public:
    DoubleMe() { me+=me;)
    int GetMe() {return me;}
private;
    cNumber() { me=1;}
    int me;
}

so in Max i have.

import "number.cpp"
extern 
   function GetMe%()
   function DoubleMe()
end extern

I have also tried

import "number.cpp"
extern 
   function cNumber:GetMe%()
   function cNumber:DoubleMe()
end extern

and it responds with "Identitfier GetMe not found"
