Sorry, apparently -fwritable-strings was depreciated, not -Wwrite-strings;
however regardless, since there's no such thing as a string type in C/C++,
strings are arrays of char, so it would seem most consistent to treat them
as such by default.  Which means by default, you can't write to a string
literal/static-const, although may specify their static const literal value:
