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 IN_CTYPE_DOMAIN to 1 should let any compiler worth its salt   eliminate the && through constant folding."   Solaris defines some of these symbols so we must undefine them first.  */#if defined STDC_HEADERS || (!defined isascii && !defined HAVE_ISASCII)#  define IN_CTYPE_DOMAIN(c) 1#else#  define IN_CTYPE_DOMAIN(c) isascii(c)#endif#if !defined (isspace) && !defined (HAVE_ISSPACE)#  define isspace(c) ((c) == ' ' || (c) == '\t' || (c) == '\n' || (c) == '\f')#endif#if !defined (isprint) && !defined (HAVE_ISPRINT)#  define isprint(c) (isalpha(c) || isdigit(c) || ispunct(c))#endif#if defined (isblank) || defined (HAVE_ISBLANK)#  define ISBLANK(c) (IN_CTYPE_DOMAIN (c) && isblank (c))#else#  define ISBLANK(c) ((c) == ' ' || (c) == '\t')#endif#if defined (isgraph) || defined (HAVE_ISGRAPH)#  define ISGRAPH(c) (IN_CTYPE_DOMAIN (c) && isgraph (c))#else#  define ISGRAPH(c) (IN_CTYPE_DOMAIN (c) && isprint (c) && !isspace (c))#endif#if !defined (isxdigit) && !defined (HAVE_ISXDIGIT)#  define isxdigit(c)	(((c) >= '0' && (c) <= '9') || ((c) >= 'a' && (c) <= 'f') || ((c) >= 'A' && (c) <= 'F'))#endif#undef ISPRINT#define ISPRINT(c) (IN_CTYPE_DOMAIN (c) && isprint (c))#define ISDIGIT(c) (IN_CTYPE_DOMAIN (c) && isdigit (c))#define ISALNUM(c) (IN_CTYPE_DOMAIN (c) && isalnum (c))#define ISALPHA(c) (IN_CTYPE_DOMAIN (c) && isalpha (c))#define ISCNTRL(c) (IN_CTYPE_DOMAIN (c) && iscntrl (c))#define ISLOWER(c) (IN_CTYPE_DOMAIN (c) && islower (c))#define ISPUNCT(c) (IN_CTYPE_DOMAIN (c) && ispunct (c))#define ISSPACE(c) (IN_CTYPE_DOMAIN (c) && isspace (c))#define ISUPPER(c) (IN_CTYPE_DOMAIN (c) && isupper (c))#define ISXDIGIT(c) (IN_CTYPE_DOMAIN (c) && isxdigit (c))#define ISLETTER(c)	(ISALPHA(c))#define DIGIT(c)	((c) >= '0' && (c) <= '9')#define HEXVALUE(c) \  (((c) >= 'a' && (c) <= 'f') \	?
