This is not correct.  For non-static member functions the default 
calling convention is "thiscall" which is more efficient than "cdecl" 
(the "this" pointer is passed in a register, and the called function 
increments the return stack pointer over the arguments).  Personally I 
don't see the point in changing the calling convention for a non-static 
member function.
