I guess someone should point out that some commercial compilers (Sun's 
comes to mind) issue warnings for unreachable code. IMO this would make 
a nice improvement to gcc.

As far as redundant code, though, redundant code can be more readable 
than the alternative (I've several times caught myself writing redundant 
code and hoping gcc would fold it in optimization).
