ci.freebsd.org 's FreeBSD-head-amd64-gcc #5973 ( -r334645 ) is
the last build that worked. #5973 ( -r334647 ) is the first that
failed.

Maybe pmc forces -Werror and/or -Wredundant-decls since its new
use of include <iostream> is what seems to matter for the failure.

But, prior to that additional include, FreeBSD-head-amd64-gcc was
building fine on ci.freebsd.org .


(I have no control over ci.freebsd.org builds, which is the
context I reported the problem for.)
