I'm not sure I follow. Gcc 3.3 emits the warning whether the code is dead or not.
Perfectly legitimate code (written in good style) fails to compile with -Wall
-Werror in 3.3.1 while it did build in 3.2.2 --- isn't that a regression?
That it warns before GCC finds the warning before the code is known to be dead
is obvious, but that does not make it less of a bug, does it?
And about the duplicate: I was told in 4210 to open a new bug. I hope I didn't
misunderstand Wolfgang Bangerth's comment. Please bear with me if I'm confused.
