-/* Taking advantage of the C99 mutual-exclusion guarantees for the various

- * (w)chars, we can place each in one of the following mutually-exlusive
- * subsets. Since there are less than 16, we can store the data for
- * each (w)chars in a nibble. In contrast, glibc uses an unsigned int
- * per (w)char, with one bit flag for each is* type. While this allows
- * a simple '&' operation to determine the type vs. a range test and a
- * little special handling for the "blank" and "xdigit" types in my
- * approach, it also uses 8 times the space for the tables on the typical
- * 32-bit archs we supported.*/
