Do you know which > version of FreeBSD changed the signature? Care to write a patch? Unfortunately, I don't know in which version of FreeBSD that changed. I rarely fire up that virtual machine (only in rare cases when I want to verify some change to Git also builds/runs/whatever on FreeBSD), so I haven't really been paying attention to it. I know that this warning was present in 11.1 (and I'm guessing all of 11.x), but I don't recall if it manifested in 10.x. I guess it shouldn't be too hard to install various versions of FreeBSD to determine this, but it would be quite time-consuming. I'm not very familiar with FreeBSD-land, but I would hope there would be an easier way to determine when it changed than by installing old versions. Does FreeBSD have historic package repositories (containing headers, for instance) which one could consult instead?
