Subject: [Bug c++/13879] New: Error when doing an explicit specilization within a class
X-Bugzilla-Reason: CC
X-SW-Source: 2004-01/txt/msg03372.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

code is (in file fact.cc):
// meta factorial - example for generative programming by James O. Coplien
// the Test class was added to demonstrate the gcc compilation error.

#include <stdio.h>

class Test {
public:
  template<int n>
  struct Fact 
  {
    enum {RET = Fact<n-1>::RET*n};
  };
  
  template<>
  struct Fact<0>
  {
    enum{RET = 1};
  };

  void Print()
  {
    printf("Fact<7>=%d\n", Fact<7>::RET);
  }
};

int main()
{
  Test t;
  
  t.Print();
  return 0;
} 

command line:
gcc fact.cc

compilation error:
fact.cc:14: explicit specialization in non-namespace scope 'Test'

Note: the same code was compiled using sun compiler:
cc fact.cc
Both compilation and execution were successful.
