I should have given a more complete description of reserved names:
* Any identifier containing a double underscore.
* Any identifier beginning with an underscore and a capital letter.
* All names beginning with an underscore in the global namespace.

Since, stl_alloc holds a pointer to the real allocator, shouldn't
stl_alloc<void, ...> also have such a pointer and the appropriate
constructors?
You should partially specialize:
template<class Alloc>
class stl_alloc<void, Alloc> { ... };
Also, the typedefs and rebind template of stl_alloc<void, ...> should be
public.
My personal preference would be to spell out stl_allocator entirely rather
than abbreviating it to stl_alloc.

change class name: stl_alloc -> stl_allocator

partially specialize stl_allocator

macros are all prefixed with BOOST_MEMORY to avoid conflicts.
everything goes into namespace boost::memory, rather than directly in namespace boost.

[45190]:

Update GC Allocator specification. The following is minimum specification for GC Allocator:

typedef void (*DestructorType)(void* data);
concept GCAllocator
{
    // Allocate memory without given a cleanup function
    void* allocate(size_t cb);
    // Allocate unmanaged memory with a cleanup function
    void* unmanaged_alloc(size_t cb, DestructorType fn);
    // Commit unmanaged memory to be managed.
    void* manage(void* p, destructor_t fn);
    // Deprecated: allocate memory with a cleanup function
    void* allocate(size_t cb, DestructorType fn) {
       return manage(unmanaged_alloc(cb, fn), fn);
    }
    // Cleanup and deallocate all allocated memory by this GC Allocator
    void clear();
    // Swap two GCAllocator instances
    void swap(GCAllocator& o);
};
