      58     "... Some ctype macros are valid only for character codes that
      59     isascii says are ASCII (SGI's IRIX-4.0.5 is one such system --when
      60     using /bin/cc or gcc but without giving an ansi option).  So, all
      61     ctype uses should be through macros like ISPRINT...  If
      62     STDC_HEADERS is defined, then autoconf has verified that the ctype
      63     macros don't need to be guarded with references to isascii. ...
      64     Defining isascii to 1 should let any compiler worth its salt
      65     eliminate the && through constant folding."
      66     Solaris defines some of these symbols so we must undefine them first. */
