Bill, do your really manage to succeed with that?

We originally strived for a zero warning policy, but EGCS -- not our
code! -- still has way to many bugs which trigger incorrect warnings.


For example, as I have reported back last December, even the one-liner
  main() { for(int i=1;;i++); for(int i=1;;i++); }
causes
  warning: declaration of `i' shadows previous local
with egcs-1.1 and egcs-current when -Wshadow is used.
