SYNOPSIS
   Namespaces
       namespace __detail
           Implementation details not part of the namespace __gnu_cxx
           interface.
       namespace typelist

   Classes
       struct __alloc_traits

       struct __common_pool_policy
           Policy for shared __pool objects.
       class __mt_alloc
           This is a fixed size (power of 2) allocator which - when compiled
           with thread support - will maintain one freelist per size per
           thread plus a global one. Steps are taken to limit the per thread
           freelist sizes (by returning excess back to the global list).
       class __mt_alloc_base
           Base class for _Tp dependent member functions.
       struct __per_type_pool_policy
           Policy for individual __pool objects.
       class __pool
           Data describing the underlying memory pool, parameterized on
           threading support.
       class __pool< false >
           Specialization for single thread.
       class __pool< true >
           Specialization for thread enabled, via gthreads.h.

Function Documentation
   template<typename _ToType , typename _FromType > _ToType
       __gnu_cxx::__static_pointer_cast (_FromType * __arg) [inline]
       Casting operations for cases where _FromType is a standard pointer.
       _ToType can be a standard or non-standard pointer.

   template<typename _ToType , typename _FromType > _ToType
       __gnu_cxx::__static_pointer_cast (const _FromType & __arg) [inline]
       Casting operations for cases where _FromType is not a standard pointer.
       _ToType can be a standard or non-standard pointer. Given that _FromType
       is not a pointer, it must have a get() method that returns the standard
       pointer equivalent of the address it points to, and must have an
       element_type typedef which names the type it points to.
