51  * these are not present on Solaris.  Note that the standard requires
52  * iswascii to be a macro, so it is defined in our headers.

54  * We renamed (per Solaris) iswideogram, iswspecial, iswspecial to the
55  * equivalent values without "w".  We added a new isnumber, that looks
56  * for non-ASCII numbers.
