Hi Harry,

I got following build error on FreeBSD + gcc 4.9.4 combo.

$ gcc -v
Using built-in specs.

$ 

I think it is nothing do with FreeBSD. Looks like gcc < 5 will hit this
issue. But the strange part is patchwork test report shows as compilation success.

If you don't have any better fix, I can apply the following on pull
request. If you have something better send it as patch.
