00002  * SETUP: Make sure we define everything we will need.
00003  *
00004  * We have create three types of pools:
00005  *   1) MEMPOOL - standard pools
00006  *   2) MALLOC_MEMPOOL - to be used by mem_malloc in mem.c
00007  *   3) PBUF_MEMPOOL - a mempool of pbuf's, so include space for the pbuf struct
00008  *
00009  * If the include'r doesn't require any special treatment of each of the types
00010  * above, then will declare #2 & #3 to be just standard mempools.
