[Bug other/28322] GCC new warnings and compatibility

I agree with most of what you say but, unfortunately, unless someone that can
approve a patch for this also agrees, it is pointless even to think about how
to implement it. Also, bugzilla is not closely followed by GCC maintainers
(except Andrew Pinski, but Andrew is not human, he lives in bugzilla's mind).
You may have better luck in gcc@gcc.gnu.org. (if you get ignored, you may need
to try a few times, though).

I would recommend to raise one point at a time. For example,

1. GCC should ignore unknown -Wno-* options if no other warnings are to
   be issued.  This is always correct since the only effect of such an
   option would be to suppress warnings which might otherwise be
   issued.  If no warnings are to be issued at all then treating even
   an unknown suppression as a no-op is clearly correct.

If you get the appropriate maintainer to agree on this point, I volunteer to
implement it for GCC 4.3 (subject to my free time, but it will be high in my
priority list). You may ever convince the release manager to add it to GCC 4.2
before it is released.

Good luck!
