Follow-up Comment #15, bug #23240 (project lwip):

I thought about that and decided that as the user was probably expecting an
unsigned value, it was better to cast it to unsigned.

What I will do instead is retrieve the value of recv_avail, round it up to
zero if it is negative, and return that as an unsigned value.  I think that
should make sense in the circumstances.
