Building a kernel using W=1 with gcc 4.3.2 failed like this: cc1: error: unrecognized command line option "-Wpacked-bitfield-compat" Make use of this option dependent on the compiler. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Dave Jones <davej@redhat.com> --- I do not see this a stable material - people running stable kernels have less value of W=1. And the amount of warnings are outright silly. We should really divide this up a bit so W=1 is semi usefull.
