   Both Sun and Pgi on Linux correctly put typeinfo into the std
   namespace, but function_base keys off the
   BOOST_NO_EXCEPTION_STD_NAMESPACE macro instead of the
   BOOST_NO_STD_TYPEINFO macro.  The attached patch changes
   function_base to use the typeinfo macro.  Because eVC 4.2 doesn't
   put typeinfo into the std namespace, I need to define
   BOOST_NO_STD_TYPEINFO only for this eVC version.

   Implement an optimization that David Abrahams and myself came up with,
   where Boost.Function uses a bit in the vtable pointer to indicate when
   the target function object has a trivial copy constructor, trivial
   destructor, and fits within the small object buffer. In this case, we
   just copy the bits of the function object rather than performing an
   indirect call to the manager.

   This results in a 60% speedup on a micro-benchmark that copies and
   calls such function objects repeatedly.

   Add 'and later versions' to support info for GCC and Visual C++. Fixes
 #2847.

   I didn't explicitly specify the versions since no one's updating this
   list and it's highly unlikely that a future version will break this. The
   same could probably be done for the other compilers but I don't know
   them very well so I'm leaving them alone.
