-Wall does not include -Wwrite-strings. The docs are also correct but badly
worded.

When compiling C, give string constants the type @code{const
[EMAIL PROTECTED] so that
-copying the address of one into a [EMAIL PROTECTED] @code{char *}
-pointer will get a warning; when compiling C++, warn about the
-deprecated conversion from string literals to @code{char *}. This
-warning, by default, is enabled for C++ programs.
-These warnings will help you find at
-compile time code that can try to write into a string constant, but
-only if you have been very careful about using @code{const} in
-declarations and prototypes. Otherwise, it will just be a nuisance;
-this is why we did not make @option{-Wall} request these warnings.
