[Bug c++/17936] New: [4.0 regression] Instantiation of specialization rejected

[reichelt at gcc dot gnu dot org]

The following code snippet does not compile any more on mainline:

==================================
template<int, int N> struct A
{
    void foo();
};

template<int N> struct A<1, N>
{
    void foo();
};

template<> void A<1, 2>::foo();
==================================

vectors.cc:11: error: prototype for `void A<1, N>::foo() [with int N = 2]' does
not match any in class `A<1, 2>'
vectors.cc:8: error: candidate is: void A<1, N>::foo() [with int N = 2]
vectors.cc:11: error: `void A<1, N>::foo() [with int N = 2]' and `void A<1,
N>::foo() [with int N = 2]' cannot be overloaded
vectors.cc:11: error: prototype for `void A<1, N>::foo() [with int N = 2]' does
not match any in class `A<1, 2>'
vectors.cc:8: error: candidate is: void A<1, N>::foo() [with int N = 2]
vectors.cc:11: error: `void A<1, N>::foo() [with int N = 2]' and `void A<1,
N>::foo() [with int N = 2]' cannot be overloaded

This was caused by Mark's patch

Mark, could you please have a look?
