/*
 * SETUP: Make sure we define everything we will need.
 *
 * We have create three types of pools:
 *   1) MEMPOOL - standard pools
 *   2) MALLOC_MEMPOOL - to be used by mem_malloc in mem.c
 *   3) PBUF_MEMPOOL - a mempool of pbuf's, so include space for the pbuf struct
 *
 * If the include'r doesn't require any special treatment of each of the types
 * above, then will declare #2 & #3 to be just standard mempools.
