[lwip-users] htons VS HTONS (Fw: MALLOC vs. malloc: maybe use __builtin_constant_p?)

[Leon Woestenberg]

Hello,

the NetBSD mailing list discussed a similar issue to what we recently
discussed about: The compile-time evaluation of the htons() functions
which would be nice if they evaluate as macro's if the argument is a
constant.

I'll try to see if they found a nice solution for it.

Leon.
