[lwip-devel] [bug #49827] wrong cast to size_t on 16-bit x86 architecture

[Alexander]

Follow-up Comment #15, bug #49827 (project lwip):

I have test another 16Bit compable compiler (DigitalMars):

printf("%p\n", &lwip_cyclic_timers[i]);
printf("%p\n", LWIP_CONST_CAST(void*, &lwip_cyclic_timers[i]));

and got the results:
317B:000C
0000:000C

And if We start talk about warnings, there are some places in LwIP
(api_msg:1520, dnc.c:1223)
where compiler warns if int is 16 bit long:

if ((int)(res_idx + lwip_htons(ans.len)) > 0xFFFF)
dns.c(1223): Warning! W124: Comparison result always 0

By standart: int Capable of containing at least the [−32767, +32767] range.
