at ctype.h in GNU libc, and while there's a complicated mess of macros and 
functions, somewhere in the definition of isspace() there's an array being 
indexed.

See if isspace((unsigned char) *str) gets rid of the warning.

The line array[c] is very likely a bug, because the type char can be signed or 
unsigned—it's up to the compiler. If char is signed, then it's possible for c 
to be negative, in which case accessing a negative array index leads to 
Undefined Behavior.

This change is not in line with the coding style of this file. Please change it to:

isspace ((unsigned char) s[r + b])

Try to avoid superfluous parenthesis.

          {
            s[r + b] = '\0';
            ++b;
          }
          b = ls - 1;
-        while (b > 0 && isspace (s[r + b]))
+        while (b > 0 && isspace((unsigned char)(s[r + b])))
Likewise.
          {
            s[r + b] = '\0';
