There is no "of course" here. The GNAT implementation happens to call the
underlying allocation routine in the RTS directly because this is more
straightforward, and there is no attempt to make GNAT runtime routines
portable to non-GNAT Ada compilers.

But it is a trivial excercise to rewrite this so that it uses an Ada
allocator instead of the direct call if you want to be completely portable.
