    tcsh - Work around gcc-5 bug
    * GCC-5 improperly tries to optimize tcsh's calloc() replacement into a
      tail-jmp to tcsh's calloc.  It tries to optimize the malloc+memset
      sequence into calloc, inside calloc itself.
      This is really a bug in GCC-5 but work around it for now by hacking
      tcsh's calloc().
