 Hi,

 Usage of either boost::pool_allocator or boost::fast_pool_allocator with
 std::allocate_shared can cause compile errors on the g++4.7, 4.8, 4.9.
 There is much more detailed information on the stack overflow question I
 made: [http://stackoverflow.com/questions/26396293/boost-pool-allocators-

 wont-compile-with-stdallocate-shared-in-g]

 Code exhibiting the error:

 {{{
 #include "boost/pool/pool.hpp"
 #include "boost/pool/pool_alloc.hpp"

 #include <memory>

 int main(int argc, char** argv)
 {
   auto fails = std::allocate_shared<int>(
 boost::fast_pool_allocator<int>() );

   auto works =
 std::allocate_shared<int>(boost::fast_pool_allocator<int>(), 5);
 }
 }}}

 Simply put boost allocators are still specified using the c++98 style and
 this causes g++ to fail for the versions of g++ mentioned above. However
 it should be noted that g++ 5.0 does compile correctly and this implies
 that updating is not necessarily mandatory. I have made this ticket so
 that the appropriate people can make a determination about whether to fix
 this or not. Also note that changing to the c++11 allocator style seems to
 be straightforward.
