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. Suggested by Paul Eggert and Jim Meyering. Signed-off-by: Eric Blake <eblake@redhat.com>
