           Summary: clang misparses "//*" in C89 mode
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: preprocessor
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: sharparrow1 at yahoo.com

int a(int x) {return x//**/;

In C99/GNU/C++ modes, this should return x+x.  However, in C89 mode, this
should return x.  clang currently gets this wrong in C89 mode.

It would probably be a good idea to warn for this construct.
