<tr1/hashtable> header, where a friend class template std::tr1::__detail::_Map_base is declared with the wrong template parameters. GCC doesn't catch the problem, so Clang does a little back-flip to avoid diagnosing just this one instance of the problem. llvm-svn: 100790

// libstdc++ 4.2.x contains a bug where a friend struct template
|
|
// declaration for std::tr1::__detail::_Map base has different
|
|
// template arguments than the real declaration. Clang has an
|
|
// egregious hack to work around this problem, since we can't modify
|
|
// all of the world's libstdc++'s.
