"... 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."
Bruno Haible adds:
"... 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." */
