This is upstream problem with gcc 6.x being discussed in this thread:
http://lists.nongnu.org/archive/html/gpsd-dev/2016-09/msg00082.html

That said on my Fedora 24 I'm easily seeing the same problem trying to build gpsd.

The only work-around for gcc 6.x now is adding "-std=gnu++98" to both CFLAGS and CXXFLAGS.
I'll try to come up with something for BR in the meantime.
