As far as I see, dword_ptr_t is defined as follows:
#if defined(WINVER) && (WINVER < 0x0500)
  typedef DWORD dword_ptr_t;
  typedef ULONG ulong_ptr_t;
#else
  typedef DWORD_PTR dword_ptr_t;
  typedef ULONG_PTR ulong_ptr_t;
#endif

So, it seems that in WINVER is not defined correctly in your project.
Define it globally as 0x0501.
