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