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.

1. change class name: stl_alloc -> stl_allocator

2. partially specialize stl_allocator

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

1. 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);
};

2. testExceptionSemantics

1. BOOST_MEMORY_NO_STRICT_EXCEPTION_SEMANTICS.
2. gc_alloc defect: Segment fault in 64bits platform.

As with #1885, this is not an appropriate use of Trac.
