  Hi Paolo (again) and Jonathan,

  Thanks for offering to add the missing functionality, Jonathan. 

  I was wondering if there might be an interest to add _AllocatorConcept to
boost_concept_check.h. Asides from helping with diagnosing allocator
non-compliance, it might help with the more common case of template parameter
mixup (it's not impossibly hard to code - as an STL client -
some_stl_container<param0, param1, param2, param3> while getting them mixed up
and sending as Allocator something completely different).
  If there's an interest, I could try to get a go at this in a few weeks.
