Hi Ian. Thank you. Sorry about the missing data. The version is 4.2.0. I file the bug report shortly. Thanks jbm -----Original Message----- From: Ian Lance Taylor [mailto:iant@xxxxxxxxxx] Sent: Thursday, June 12, 2008 4:36 PM To: John Morrison Cc: gcc-help@xxxxxxxxxxx Subject: Re: Wno-packed flag not working?

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
