--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
I can put together a patch to define the assignment.  Containers need to be
assignable in order to be used as elements in other containers or as members of
classes/structs that are.  Otherwise, the limitation has to be worked around by
hand-coding the assignment for hash_map (and anything else) in the class/struct
of which it's a member.  I've had to do that twice already and it's error-prone
each time.
