+ * 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.
