commit b47152a4910efc6e4a6d176684807b85008909c8
Author: Nysal Jan K.A <jnysal at in.ibm.com>
Date:   Thu May 15 19:10:11 2014 +0530

    Fix vecblklen validation failure on power arch
    
    The default char datatype on power arch is unsigned.
    The following signed vs unsigned comparison thus fails:
    
      if (*p != -1) {
        errs++;
        fprintf( stderr, "[%d,%d,%d]expected -1 but saw %d\n",
                 i, j, k, *p );
      }
    
    Explicitly specify a signed char
    
    Closes #2091
