[issue14656] Add a macro for unreachable code

[Martin v. Löwis]

Martin v. Löwis <martin at v.loewis.de> added the comment:

Sorry, I missed the patch. I still fail to see the problem that this solves: what compiler produces "control reaches end of non-void function without return" for the current code? ISTM that your patch has the potential of *introducing* such a warning on some compilers, since you are removing the return statement (and the compiler may not be smart enough to determine that Py_FatalError does not return).
