May this be caused by passing dummy pointer set to 0 to the
ignore_unused_variable_warning() function in core/access.hpp?

If you agree I'd like to get rid of the pointers and instead use:

detail::signature_getset_dimension const& dummy =
detail::signature_getset_dimension()

of course if this is still needed. Otherwise we could think about removing
them.

I may be mistaken but AFAIR I implemented a few overloads of some function
with different number of template parameters somewhere and everything works
(tests pass on all tested platforms).
Is it possible that this was a problem for some old versions of GCC for
which the support was dropped?
