  12 // bthledef.h from Win8 SDK has a couple of issues when used in a Win32 app:
  13 // * line 420: usage of "pragma pop" instead of "pragma warning(pop)"
  14 // * line 349: no CALLBACK modifier in the definition of
  15 // PFNBLUETOOTH_GATT_EVENT_CALLBACK.
  16 //
  17 // So, we duplicate the definitions we need and prevent the build from including
  18 // the content of bthledef.h.
