Milestone:  Boost 1.39.0      |   Component:  smart_ptr
  Version:  Boost 1.38.0      |    Severity:  Problem

------------------------------+---------------------------------------------
 Attached is an implementation of a free shared_from_this function, plus a
 non-template enable_shared_from_this_base class which can only be used
 with the free shared_from_this function.  The free function will also work
 with the usual enable_shared_from_this template.  It is implemented on top
 of the existing enable_shared_from_this class, and so requires no
 modification of the existing smart_ptr code.

 This scheme has the advantage of simplicity, since the "curiously
 recurring template pattern" is not needed.  It also "just works" if you
 have a class hierarchy that looks like "X is derived from Y is derived
 from enable_shared_from_this_base" and want to use shared_from_this with
 both X and Y.

 I've only tried it with gcc 4.3.
