        * gcc-interface/utils2.c (build_call_alloc_dealloc_proc): New
        helper for build_call_alloc_dealloc with arguments to be interpreted
        identically.  Process the case where a GNAT_PROC to call is provided.
        (maybe_wrap_malloc): New helper for build_call_alloc_dealloc, to build
        and return an allocator for DATA_SIZE bytes aimed at containing a
        DATA_TYPE object, using the default __gnat_malloc allocator.  Honor
        DATA_TYPE alignments greater than what the latter offers.
        (maybe_wrap_free): New helper for build_call_alloc_dealloc, to
        release a DATA_TYPE object designated by DATA_PTR using the
        __gnat_free entry point.
        (build_call_alloc_dealloc): Expect object data type instead of naked
        alignment constraint. Use the new helpers.
        (build_allocator): Remove special processing for the super-aligned
        case, now handled by build_call_alloc_dealloc.  Pass data type instead
        of the former alignment argument, as expected by the new interface.
        * gcc-interface/gigi.h (build_call_alloc_dealloc): Adjust prototype
        and comment.
        * gcc-interface/trans.c (gnat_to_gnu) <case N_Free_Statement>:
        Remove special processing for the super-aligned case, now handled
        by build_call_alloc_dealloc.  Pass data type instead of the former
        alignment argument, as expected by the new interface.

        * gnat.dg/align_max.adb: New test.
