(_D_EXACT_NAMELEN): Renamed from NLENGTH, for
convenience on GNU systems. All uses changed. Don't bother looking for any dirent.h substitute other than ndir.h. (D_INO): Remove unnecessary parentheses. (IN_CTYPE_DOMAIN, ISGRAPH, ISPRINT, ISALNUM, ISALPHA): (ISCNTRL, ISLOWER, ISPUNCT, ISSPACE, ISUPPER, ISXDIGIT): (ISDIGIT_LOCALE, TOLOWER, TOUPPER): Remove. All uses changed to ctype.h equivalents. (isblank): Renamed from ISBLANK. Check for HAVE_DECL_ISBLANK too. All uses changed.

- "... Some ctype macros are valid only for character codes that
- isascii says are ASCII (SGI's IRIX-4.0.5 is one such system --when
- using /bin/cc or gcc but without giving an ansi option). So, all
- ctype uses should be through macros like ISPRINT... If
- STDC_HEADERS is defined, then autoconf has verified that the ctype
- macros don't need to be guarded with references to isascii. ...
- Defining isascii to 1 should let any compiler worth its salt
- eliminate the && through constant folding."

- "... Furthermore, isupper(c) etc. have an undefined result if c is
- outside the range -1 <= c <= 255. One is tempted to write isupper(c)
- with c being of type `char', but this is wrong if c is an 8-bit
- character >= 128 which gets sign-extended to a negative value.
- The macro ISUPPER protects against this as well." */
