Wno-packed flag not working?

[John Morrison]

Hi Ian.

Thank you.  Sorry about the missing data.  

The version is 4.2.0.

I file the bug report shortly.

Thanks

Probably it should.  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.
