Replacing the allocator with _Alloc::rebind<std::pair<key_type, iterator>::other, yielding the line

  typedef std::map< key_type, iterator, cmp, _Alloc::rebind<std::pair<key_type, iterator>::other > map_type;

doesn't work for me (see below for the error).

I came across this forum post

  http://forums.sun.com/thread.jspa?threadID=5286643

prompting me to try and replace that line with

  typedef std::map< key_type, iterator, cmp, std::allocator< std::pair<const key_type, iterator> > > map_type;

which works (compiles and succeeds) -- both with apple's gcc and fsf gcc.
