It occurred to me that you may be a little surprised that the patch
actually prevents the warning from occurring. If you have any doubts,
I can assure you that it does. Clang differentiates between 0 as an
rvalue, 0 from an enum literal and 0 resulting from evaluating a macro
expression (including a function-like macro with deep nesting).
