FreeBSD/src 2c3f47a (r352435) — lib/atf/libatf-c++ Makefile, lib/googletest Makefile.inc
Another round of attempting to squelch -Wdeprecated-declarations, which has become very trigger-happy with libc++ 9.0.0. It does not help that gcc's implementation of this warning is even more trigger-happy, in the sense that it already warns on the declaration itself, not when you are using it. This is very annoying with our use of -Wsystem-headers. That should really be disabled for gcc.
