             Bug #: 12414
           Summary: gcc compatibility: error: number of arguments doesn't
                    match prototype
           Product: clang
           Version: 3.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: -New Bugs
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: afriza.na at gmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


void taskmain(int argc, char* argv[]);

void taskmain() {
  printf("libtask");
}

For the above code, gcc reports error and clang -std=gnu89 keeps quiet.

We really ought to be at least printing a warning here.
