The following patch is fixed the build.

}
nullptr is a C++0x feature, "_NATIVE_NULLPTR_SUPPORTED" is defined in
"C:\Program Files\Microsoft Visual Studio 10.0\VC\include\stddef.h" and it is
the symbol being checked for in other VC10 headers.
I'm not aware of any clean or portable way to detect presence of the nullptr.
