This code compiles without problems on the Unix systems.  It appears that
what the Microsoft compiler is complaining about is that a default parameter
is specified in both the declaration and the definition of a method; e.g.


    // Declaration in *.h
    void
    AffineTransform<ScalarType, NDimensions>::
    Compose(
        const Self &other,
        bool pre=0);


    // Definition in *.txx
    void
    AffineTransform<ScalarType, NDimensions>::
    Compose(
        const Self &other,
        bool pre=0)
    {...}


Can someone more knowledgeble in C++ determine whether the code here
is wrong or whether the MS compiler is wrong?  And, in either case,
what should we do about it?
