  73    each variable, which is local to the current thread if multithreaded.
  74
  75    These point into arrays of 384, so they can be indexed by any `unsigned
  76    char' value [0,255]; by EOF (-1); or by any `signed char' value
  77    [-128,-1).  ISO C requires that the ctype functions work for `unsigned
  78    char' values and for EOF; we also support negative `signed char' values
  79    for broken old programs.  The case conversion arrays are of `int's
  80    rather than `unsigned char's because tolower (EOF) must be EOF, which
  81    doesn't fit into an `unsigned char'.  But today more important is that

  91  *    ctype mapping functions map from the set of (unsigned) char
