I don't know of any such compilers, but I /can/ conceive of such.  A
(16-bit) word addressed machine where sizeof(int*) is 4 but sizeof(void*) is
6 might have the required alignment of int be 4, but the required alignment
of void* only be 2 :-(

On the other hand, it might be acceptable to say "boost::any" is not
supported on such machines.
