 133    char' values and for EOF; we also support negative `signed char' values
 134    for broken old programs.  The case conversion arrays are of `int's
 135    rather than `unsigned char's because tolower (EOF) must be EOF, which
 136    doesn't fit into an `unsigned char'.  But today more important is that
