You can simulate this on Linux by compiling with:

  BASECFLAGS="-funsigned-char"

Then:

         while (Py_ISALNUM(c) || c == '_') {
+            c = EOF; // tok_nextc can return EOF
+            printf("c: %d\n", Py_CHARMASK(c));
             c = tok_nextc(tok);
         }
         tok_backup(tok, c);



>>> eval("abcd")
c: -1
c: -1
c: -1
c: -1
c: -1
c: -1




Also, during compilation you get tons of warnings about using
char as an array subscript:

Objects/stringlib/split.h: In function ‘stringlib_split_whitespace’:
Objects/stringlib/split.h:70: warning: array subscript has type ‘char’
Objects/stringlib/split.h:74: warning: array subscript has type ‘char’
Objects/stringlib/split.h:91: warning: array subscript has type ‘char’
