Phil,

Adding -Wextra as an alias for -W is fine, but IMHO removing -W is
not.  Why invalidate people's Makefiles and configure scripts that
have worked for a decade?  For the same reason, we should not issue a
"deprecated" warning when using -W.

Just make -Wextra the *documented* way to get the extra warnings and
you'll solve the problem of explaining to newbies what the flag means.

Those who already use -W in their config already know what it does.
