Well, you are right taking care of that. I must admit I don't check that 
thoroughly even if I'm doing a lot of commits in order to reduce the PPP 
memory footprint (first), stack requirement (second) and overall code 
size (third). Sometimes we need a bit more code when we are fixing bugs 
or security issues.

I guess too, I tested in the worst case: x86_64, not stripped, using 
-ggdb (so using DWARF 2, which is huuuuge in size), and nothing gained 
so much, the lwIP core was 14016 bytes bigger in this case, that's still 
a lot less than 20 KiB considering you are probably building for a 
32-bit target and without symbols.

By the way, 20 KiB on a total of ? :)
