[Toon-members] Warnings with -Wignored-qualifiers on gcc 4.3.4

I'm just wondering if you are aware of the following warnings, and that
are they safe to ignore by using -Wno-ignored-qualifiers.

Compiling the attached source file with:
$ bash


../TooN/internal/operators.hh: In instantiation of
'TooN::Internal::MultiplyType<const double, double, 1>':

../TooN/internal/operators.hh:354:   instantiated from 'void
TooN::Operator<TooN::Internal::MatrixVectorMultiply<R, C, P1, B1, Size,
P2, B2> >::eval(TooN::Vector<Size2, Precision2, Base2>&) const [with
int Sout = 3, Pout = double, Bout = TooN::Internal::VBase, int R = 3,
int C = 3, P1 = double, B1 = TooN::RowMajor, int Size = 3, P2 = double,
B2 = TooN::Internal::VBase]'

../TooN/internal/operators.hh:43: warning: type qualifiers ignored on
function return type

This is with the TooN CVS version of today and g++ (Gentoo 4.3.4 p1.1,
pie-10.1.5) 4.3.4.

-Wignored-qualifiers is turned on by -Wextra, which I always use.
Of course, I would prefer a fix instead of hiding the warnings.
