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.) === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) _______________________________________________ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
