[Bug libstdc++/29898] New: hash_map<> lacks support for long long

["gerald at pfeifer dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The following program fails to compile with every version of GCC 4.x I
tested (including current mainline) with

  error: no match for call to '(const __gnu_cxx::hash<long long int>) (const
long   
  long int&)'

==== snip ====
  #include <ext/hash_set>

  using namespace __gnu_cxx;

  typedef long long T;

  void f() {
    hash_set<T> t;

    t.insert(1);
    t.erase(1);
  }
==== snip ====

The problem is that libstdc++ fails to define hash<long long>.
