No to -std=c99. It's >= C99 for applications; we should not prevent them from using a newer C standard.
Adding a note about the C standard version to the DPDK requirements documentation would be very nice. It only mentions a certain compiler version required. But I think that documenting the detailed build and runtime requirements (and why they are that way) is another task.
