--- Comment #6 from Peter Eisentraut <peter_e at gmx dot net> --- This particular case is in system headers, but there are other cases that are not, so this isn't going to help in general. I think this is a legitimate way to write a function-like macro that has a side-effect and a return value, and the warning is bogus.
