I'm saying that supporting the official language spec makes more sense
than attempting to support a multitude of divergent interpretations of the
spec (i.e. gcc, clang, coverity etc.)
I'm also saying that the reason why we use -std=gnu89 is that existing
code was written in that language, not in ad hoc languages comprised of
collections of extensions that change with every release.

Thank you for checking. I found a free version that's only 6 weeks old:
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2583.pdf
It will be interesting to see whether 6.7.11.5 changes once the various
implementations reach agreement.
