[lwip-devel] [patch #7683] u32_t should be time_t in some cases

[Simon Goldschmidt]

Follow-up Comment #3, patch #7683 (project lwip):

> I wondered if LWIP actually makes assumptions about times being 32-bits

Yes, it does. 32 bit are enough in most cases as we only need the time
difference. If timers are called often enough, even 16 bit would suffice. The
only problem I could think of with that would be SNMP, but I'm not sure.

I guess that port might either rely on time being 32 bit (I would doubt that,
however), or the original makefiles don't spit out a warning when implicitly
converting. Would you mind creating a patch to see what would need to be
changed?
