When template aliases become available, to use them you'll need to
replace 'rebind_alloc' which will break any code which uses the
'other' member. If you used a different name then you could leave that
in alongside the template alias so that existing code would continue
to work. It'd also have been a more useful error message, if it just
said that 'rebind_alloc' isn't available, I'd have instantly known
what the issue was, instead there was an odd error about 'value_type'.
