            Bug ID: 25211
           Summary: -dumpversion commandline option useless
           Product: clang
           Version: trunk
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: -New Bugs

    Classification: Unclassified

No matter what version of CLang I use (I tried 3.4.2, 3.5, 3.8 (trunk)), `clang
-dumpversion` always answers "4.2.1" (all hail Douglas Adams).

It would nevertheless be useful, e.g. for building macros in Makefiles in order
to differentiate available warning switches, if this option gave a real/useful
information (e.g. "3.4.2", "3.5.0", "3.8 r=12368" etc.
