          Issue ID: 14367
           Summary: Print warnings by default
           Product: D
           Version: unspecified
          Hardware: x86
                OS: Mac OS X
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: DMD
          Assignee: nobody@puremagic.com
          Reporter: shammah.chancellor@gmail.com

DMD currently does not print warning by default.  This should be changed so that people are notified of deprecated features during compilation and can start fixing them.   It will come as a surprise when these features are finally removed. There should instead be a silent flag on the compiler to suppress warnings.
