As you know, what -Wno-packed does is disable warnings of the form "packed attribute is unnecessary for field NAME". You neglected to mention which version of gcc you are using; at least in gcc 4.3 the warning you mention is controlled by -Wattributes (as can be seen by using -fdiagnostics-show-option). Probably it should be controlled by -Wpacked instead. I would encourage you to file a bug report at http://gcc.gnu.org/bugzilla/ . Thanks. Ian
