template function Ambiguity.

[FE]

I developed class vector and class matrix use mingw gcc.
then move to vs 2008 get Problem:

template<class TYPE,int DIM=3>
class Vector
..........
template<class TYPE,int COL=4,int ROW=4>
class Matrix
.............

when call Vector<double,4>*Matrix<double,4,4>

Ambiguity in
template<class TYPE,int COL,int ROW>
Vector<TYPE,COL> operator*(Vector<TYPE,ROW>&v,Matrix<TYPE,COL,ROW>
const&m)
and
template<class TYPE,int DIM,class SCALETYPE>
Vector<TYPE,DIM> operator*(Vector<TYPE,DIM> const&v,SCALETYPE t)

vs2008 bug or Correct?(mingw gcc is pass).
how can I Solve this and don't loss Flexibility on operator*?

You have an error on line 42 of your code.

We have no idea what any of the code in question looks like, and
we're not mind readers.

Please post a minimal, *COMPILABLE* (yes, one that generates
the error above is fine) example that exhibits the behavior in
question.

Please see the FAQ, in particular FAQ 5.8
