Hi

     Here is another proposal with:
- No attempt to remove const key
- No attempt to use assignment operator
- noexcept move constructor; I slightly modify a static assertion so that it
checks that _M_bucket_index is noexcept qualified which depends on the
noexcept qualification of the functors involved in bucket computation

Tested under Linux x86_64.

Ok to commit ?
Yes, this is OK for trunk.  Thanks very much!

Patch applied.

Note that I haven't updated the C++11 status table. AFAIK you might do so before 4.9 release to report C++11 allocator support in std::set/map
