Thanks for the reports. Thankfully they can be safely ignored.
The first one is a collection of warnings generated by the DPDK build step;
they relate to a compiler hint that a function does not return and the specific
C variant doesn't support it; it's harmless for now, but probably should be
looked at since it suggests DPDK is using C primitives from a C version
different from that we're compiling, or similar.
The second is just notices that some .api files have not yet updated how they
deal with variable sized arrays; still supported, though perhaps for the next
release we should consider cleaning those up.
Chris.

No idea if it is anywhere critical or if someone has created reports for this
in the past.
