"... 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."

Solaris defines some of these symbols so we must undefine them first. */
