    include              ctype.h 
    lib/libc/gen         isctype.c tolower.c toupper.c 
  Log:
  It is not acceptable to index the array out of bounds if an illegal index
  is passed to a ctype function or macro.  Undo the last commit.  Emplace an
  explicit range check for the integer passed to the ctype macros and
  functions rather then underflowing or overflowing the array.  Currently
  return 0 if the integer is out of range (it might be more appropriate to
  assert).
