/* Jim Meyering writes:
|

|
|
"... 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." */
