inet_ntop: guard extra work by IF_LINT No need to penalize the code just to silence a gcc warning, so follow the conventions used elsewhere in gnulib. Clients that want to use extra warnings should also be using -Dlint. * lib/inet_ntop.c (inet_ntop6): Mark spurious initialization, for better code generation when not checking for warnings.
