--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-12-24 14:11:00 UTC --- Do we want to define mt_allocator in v7? Is it worth keeping all the ext allocators in the library forever? If not, we could conditionally define them only when configured for v6, which would "solve" this problem.
