[Bug c++/14912] Do not print default template arguments in error messages

["giovannibajo at libero dot it" <gcc-bugzilla at gcc dot gnu dot org>]

I'll try to do this. This is a simple testcase:

---------------------------
template <class T, int N=0, int X=1>
struct A
{
   typedef typename T::x x;
};
void foo(void)
{
  A<void,0> a;
}
---------------------------
test.cc: At global scope:
test.cc: In instantiation of 'A<void, 0, 1>':
test.cc:8:   instantiated from here
test.cc:4: error: 'void' is not a class, struct, or union type

Do we want the error message to show 'A<void, 0>' or 'A<void>'? In other words, 
should GCC try and remember which arguments were really specified in the 
template-id (hard to do), or a simple check of equalness between the argument 
and the default parameter would suffice?
