At first I thought that the warning is not useful since the variable may
in fact not be unused at all -- the using declaration simply makes the
name available in the present scope.
However, then I realized that this also holds here:
----------------
void f()
{
extern int i;
}
----------------
For this code, we warn, though:
g/x> /home/bangerth/bin/gcc-4.2-pre/bin/c++ -Wunused -c x.cc
x.cc: In function ‘void f()’:
x.cc:3: warning: unused variable ‘i’
So for the sake of consistency, we should probably do the same in both
situations, whatever "the same" is here.
