Oh cool, that helps a lot. P4 is just broken here, so we can get
away with being a bit sloppy in git. I'll try just pretending
"empty symlinks" are not in the repo. Hopefully you'll have a
future commit in your p4 repo that brings back bn.h properly.
Still not sure about how I'll test this.
Thanks,
