Bug 4482 – Missing warnings when not compiling with -w

If I have series of statements such as throw new Exception("it broke"); writeln("unreachable"); and compile with -w, then naturally, this won't compile because the second statement is unreachable. That's good. However, if you do not compile with -w, no warning is printed. Shouldn't all warnings be printed regardless and -w simply choose to treat them as errors? As it is, if you're foolish enough not to compile with -w, you can easily miss stuff that's obviously wrong. I can understand the user choosing not to treat a warning as an error, but I would expect it to still be reported, and it's not.

This is not how it's defined to work in D. Warnings will only be printed if using the -w or -wi compiler switches.
