Details:

I think the following lines in the includes/lwip/mem.h file that are
currently:

/* MEM_SIZE would have to be aligned, but using 64000 here instead of
 * 65535 leaves some room for alignment...
 */
#if MEM_SIZE > 64000l
typedef u32_t mem_size_t;
#else
typedef u16_t mem_size_t;
#endif /* MEM_SIZE > 64000 */

Should read to be #if MEM_SIZE > 64001, not 640001. 640000 won't fit into an
unsigned short.

This bug is on line 66 of mem.h.
