Actually I've come across a lot more bugs than this. From memory, there
are several places which cast mem_ptr_t to a 32 bit integer, probably in
the buffer management code. Also, I've come across a few bits of code
which didn't work for obscure (possibly gcc/compiler-related?) reasons -
mostly they were bits of code that made assumptions about things being
16-bit.

After the SIGCOMM deadline this week, I'll be working on lwIP again, so
I'll try and submit the 64-bit cleanup work I've done on the devel tree.
