           Summary: importC: Global declarations are thread-local by
                    default
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: major
          Priority: P1
         Component: dmd
          Assignee: nob...@puremagic.com
          Reporter: ibuc...@gdcproject.org

In D all globals and static variables are thread-local unless explicitly
otherwise.  In C, it's the opposite.
