For such things, there are the example ports for win32 and unix in the 
contrib module in CVS. Here's the lwippools.h file of the win32 port:

/* OPTIONAL: Pools to replace heap allocation
 * Optional: Pools can be used instead of the heap for mem_malloc. If
 * so, these should be defined here, in increasing order according to
 * the pool element size.
 *
 * LWIP_MALLOC_MEMPOOL(number_elements, element_size)
 */
#if MEM_USE_POOLS
LWIP_MALLOC_MEMPOOL_START
LWIP_MALLOC_MEMPOOL(100, 256)
LWIP_MALLOC_MEMPOOL(50, 512)
LWIP_MALLOC_MEMPOOL(20, 1024)
LWIP_MALLOC_MEMPOOL(20, 1536)
LWIP_MALLOC_MEMPOOL_END
#endif /* MEM_USE_POOLS */

/* Optional: Your custom pools can go here if you would like to use
 * lwIP's memory pools for anything else.
 */
LWIP_MEMPOOL(SYS_MBOX, 22, 100, "SYS_MBOX")
