Hm... ;)

Actually the behavior with -Wwrite-strings that we had is what
gcc has too:

    typeof("123") cc = "456";
    cc[1] = 'x';
    printf("%s\n", cc);

$ gcc -Wno-write-strings ...
    4x6
$ gcc -Wwrite-strings ...
    error: assignment of read-only location 'cc[1]'

(mingw gcc 3.4.2 and 6.3.0)

Also, now tcc doesn't warn with this one anymore:
   const char cc[] = "456";
   char *p = cc;
