+ These point into arrays of 384, so they can be indexed by any `unsigned
+ char' value [0,255]; by EOF (-1); or by any `signed char' value
+ [-128,-1). ISO C requires that the ctype functions work for `unsigned
+ char' values and for EOF; we also support negative `signed char' values
+ for broken old programs. The case conversion arrays are of `int's
+ rather than `unsigned char's because tolower (EOF) must be EOF, which
+ doesn't fit into an `unsigned char'. But today more important is that
+ the arrays are also used for multi-byte character sets. */
