--- Comment #7 from David Brown <david at westcontrol dot com> ---
Could "-Wwrite-strings" be split into two options?  The warning could remain
(and become part of -Wall for C as well as C++) if the compiler can spot and
warn about attempts to write to string literals, while keeping these of type
"char[len]" as required by C.

A new option "-fconst-strings" could be put under "Code Gen Options" which
makes C string literals be type "const char[len]" for those that want it,
encouraging a slightly safer code style that is not standard C.
