Yeah, it's not ideal, but I have very little motivation (and even less time!)
to improve tr1::bind now. For C++03 code there's boost::bind and for C++11 code
there's std::bind.

It's frustrating that the TR1 spec specifies lvalues (I assumed it was the same
as std::bind). This came up in supposedly-portable code that works with MSVC's
TR1 bind.

Good thing it's fixed for std::bind.

See my comments on PR 50320

C++11 std::bind works with rvalues, as of GCC 4.5

I seem to remember that this is a known problem of the tr1 version of this
facility, per the specs. Changing the snippet like the following works:

  ...

  int main()
  {
int n = 5;
std::tr1::bind(return_int2,32,std::tr1::placeholders::_1)(n);
  }
