>Description:
See the example. What gcc notices is that classes
iterator<const A> ; and
iterator<const const A>
are identical. It then issues a warning.
The warning is unfortunate: the code is perfectly safe,
and the two declarations make sense for a non-const type.
>How-To-Repeat:
gcc warns.cc
>Fix:
Can't find the switch to turn the offensive warning off;
I can remove the cv-quals from my template instantiation,
or just ignore the warning.
