Compiler Warning (level 1) C4348

'type' : redefinition of default parameter : parameter number

A template parameter was redefined.

The following sample generates C4348:

// C4348.cpp
// compile with: /LD /W1
template <class T=int> struct A;   // forward declaration

template <class T=int> struct A { };
// C4348, redefinition of default parameter
// try the following line instead
// template <class T> struct A { };
