Maybe we should call it "config_enabled()" - the lower-case hopefully makes it clear that it acts as a C function, not a preprocessor one. Code like "if (config_enabled(IPV6))" looks reasonably readable to me. I asked G+ if they can come up with a better trick. They did well on the whole bitmask calculations, maybe somebody can figure out how to make the same macro work for both preprocessor and C code...
