/* Set up a workaround for the following problem:
* FARPROC addr = GetProcAddress(...);
* MY_FUNC func = (MY_FUNC) addr; <-- GCC 8 warning/error.
* MY_FUNC func = (MY_FUNC) (void*) addr; <-- MSVC warning/error.
* To compile cleanly with either compiler, do casts with this "bridge" type:
* MY_FUNC func = (MY_FUNC) (nt__fn_ptr_cast_t) addr; */
