+ 
+    "... 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."  */
