"... 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. */
