Not if the exported functions are declared in the def file. In this case, the names are exported in C style.

As David said a declaration like:
MyFunc @1
will export the MyFunc function in C style.

Even if the object is created in DLLMain, the function will not work properly (although no error is raised) if it uses any member variables.

If the function doesn't access any member variable or is a static member function, than it works ok.
