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