I missed iostreams. The problem seems to be a bug in gcc. This program:

#include <utility>

int main()
  std::pair<int, int*> x(0,0);
  return 0;

compiles without -std=gnu++0x, but with -std=gnu++0x gets an error:

In constr
uctor 'std::pair<_T1, _T2>::pair(_U1&&, _U2&&) [with _U1 = int, _U2 =
int, _T1 = int, _T2 = int*]':
cvt-0-to-ptr.cpp:5: instantiated from here
 invalid conversion from 'int' to 'int*'

I tried to find this in gcc bugzilla, but didn't come up with
anything. Is anyone else have any knowledge of this problem?
