[Bug c++/36655] New: unjustified warning for "extern template" when using -pedantic -std=c++0x

["gcc-bugzilla at contacts dot eelis dot net" <gcc-bugzilla at gcc dot gnu dot org>]

Consider:

  template <typename> void f() {}
  extern template void f<int>();

When compiled with:

   g++ -pedantic -std=c++0x -c t.cpp

the following warning is emitted:

   warning: ISO C++ forbids the use of ?extern? on explicit instantiations

Since extern template has already been integrated into the C++0x working paper,
I think this warning should not be emitted when using -std=c++0x, not even with
-pedantic.
