Hi and thanks for reviewing,

I seem to have somehow missed the email for this one and thought it
got lost. Sorry.

Makes sense. Bruce is right, I'm only including headers from C++, the
library is compiled using C.

It seems I didn't hit the rte_mempool.h because (at least in 1.8.0)
that the usage of PRI* is under #ifdef RTE_LIBRTE_MEMPOOL_DEBUG. It's
very likely I didn't need the first file in the list.

Anyway, I'll send a new version.
