[gpsd-dev] Fedora 22 (gcc 5) -- compile fails on memory_order_seq_cst scoping

[Jason Azze]

ESR's push (not directly related to the build failure) this morning triggered the first automated build since Jon's last changes in October.  At some point between then and now I upgraded my builder to Fedora 22. Now the build is broken on that system.

This is probably due to f22 switching to gcc 5.
