FWIW, Dore'[1] doesn't compile out of the box on FreeBSD 10.3-stable: tingo at kg-core1$ uname -a FreeBSD kg-core1.kg4.no 10.3-STABLE FreeBSD 10.3-STABLE #0 r310083: Wed Dec 14 21:00:13 CET 2016 root at kg-core1.kg4.no:/usr/obj/usr/src/sys/GENERIC amd64 Result tingo at kg-core1$ make -f Makefile.ini World Building Release 6.1 of Dore.
