           Summary: clang can't build autoconfed applications: checking size
                    of short... configure: error: cannot determine a size
                    for short
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Semantic Analyzer
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: edwintorok at gmail.com
                CC: llvmbugs at cs.uiuc.edu


The problem is that 'switch (0) case 0: case sizeof(short) == 2):;' fails too:
Switch constants must all be same type as switch value!
        switch i32 0, label %sw.epilog [
                 i32 0, label %sw.bb
                 i64 1, label %sw.bb1
        ]
Broken module found, compilation aborted!
