[lwip-devel] [patch #6699] Fixing a couple of compilation warnings(Paradigm C++)

[Bill Auerbach]

Follow-up Comment #12, patch #6699 (project lwip):

>Do we need to remove that warning? 

On a compiler with sizeof int == 2, it's real.  The int can't be 0xFFFF. 
Sure, it's always false, but it's also bad coding style when it can be done
correctly for all platforms (which lwIP is quite good at).

>I believe the proper solution would be to use C99 types from stdint.h like
uint_fast16_t or equivalent.

That will break the code on many 8- and 16-bit compilers that are not C99
compatible.
