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

[Joel Cunningham]

Follow-up Comment #17, bug #49827 (project lwip):

Simon/Dirk,

We are on the same page in regards to when to cast away const and ideally it
would never be done.  The conditions where  LWIP_CONST_CAST() are applied are
the same conditions where I'd explicitly cast away the const.

I guess I haven't worked with a toolchain configuration where  explicitly
casting away const caused a warning, but clearly it is a feature of some
compilers, possibly because most of the time const is casted away, it's not
done carefully as we discussed, but by a sloppy developer.

If I'm understanding correctly, the purpose of LWIP_CONST_CAST is to document
that the cast is well thought out and to also avoid the compiling issuing a
warning because we might have done something dangerous
