  r44918 | danieljames | 2008-04-30 08:25:20 +0100 (Wed, 30 Apr 2008) | 7 lines
  
  Change the typedef of buffered functions as it was confusing MSVC 6.5
  
  get_allocator wasn't compiling when the allocator workaround is used because it
  couldn't cast from the wrapped allocator to an allocator of another type. So
  use value_alloc_ when it's available (it's only unavailable on compilers with
  C++0x support, which don't require the workaround).
