It currently does not compile with gcc 4.9. See my original bug report here: https://lists.freebsd.org/pipermail/freebsd-toolchain/2015-March/001577.html We are trying to fix the kernel build enough with gcc 4.9 so that we can at least set up a Jenkins continuous build (with -Werror turned off initially).
