g++ template instantiation warnings?

[Brendt Wohlberg]

Is there a a -W option, or some other method, of switching off the warnings:

warning: friend declaration `void swap(class A<T> &, class A<T> &)'
warning: will not be treated as a template instantiation
warning: unless you compile with -fguiding-decls
warning: or add <> after the function name

for friend declarations *without* turning them into template instantiations
(when compiling with -fno-implicit-templates, for example)?
