OK, but...

... gcc8.0.1 on Fedora 28 the same.

I just force their dpdk submodule to dpdk master + my series and build 
with defaults.  I'm not doing anything to make it more strict or nondefault.

The quoted compiler warnings and errors are coming from lagopus actually 
using dpdk with x86_64 + gcc8.

I have a pile of lagopus fixes also required to get this far, that pile 
is still growing.
