This PR from 2011 reports that -Waddress prints unhelpful warning when the

this is easy to circumvent. I'm not so sure we actually want to disable
the warning in the case of a macro, but probably yes.
Bootstrapped/regtested on x86_64-linux, ok for trunk or should I defer to
GCC 7?

* c-typeck.c (build_binary_op): Don't issue -Waddress warnings
for macro expansions.
* gcc.dg/Waddress-2.c: New test.
I've got mixed feelings about this patch. Though we have traditionally
desired to suppress some warnings that occur due to macro expansions,
based on that, I'll ack for the trunk.
Thanks,
