Hello, Another comment from my side: When using -Wunreachable-code as a means to detect unreachable code in a switch statement I noticed that, just like the manpage says, -Wunreachable-code issues a lot of warnings when compiling with -g. There are so many warnings with "-g -Wunreachable-code" that it is impossible to see which warning is justified and which is not. The behavior with old versions of gcc was much more transparent. With gcc 3.3 I got an accurate warning for the unreachable code in the code sample I sent you. Which gcc 4.0 I only get this warning with -Wunreachable-code, but there are so many other (not useful) warnings that -Wunreachable-code is not a good solution wrt the switch statement.
