Do you have links for where these patches come from? Just so if we need to update this we know where to look

they are from DragonFly's dports collection (dports =~ FreeBSD ports): https://github.com/DragonFlyBSD/DeltaPorts/tree/master/ports/lang/gcc5/dragonfly or https://github.com/DragonFlyBSD/DPorts/tree/master/lang/gcc5. DeltaPorts is our layer above FreeBSD's ports collection. DPorts is then created by applying the patches from DeltaPorts against FreeBSD's ports.

I think you only need to update the patches in case you change the gcc version. Newer versions of gcc might already ship with those patches.

Thanks for the info! Could you add that as a comment here? We may need to update gcc one day and it'd just be good to know where the patches came from so we could perhaps pick up others if they're necessary.
