        PR ada/30684
        Backport from 4.2 branch:
        2006-11-17  Eric Botcazou  <ebotcazou@adacore.com>

        * ada-tree.h (DECL_READONLY_ONCE_ELAB): New macro.
        * decl.c (elaborate_expression_1): Test the DECL_READONLY_ONCE_ELAB
        flag in addition to TREE_READONLY to assert the constantness of
        variables for elaboration purposes.
        * trans.c (add_decl_expr): Do not dynamically elaborate padded objects
        if the initializer takes into account the padding.
        Set DECL_READONLY_ONCE_ELAB flag on variables originally TREE_READONLY
        but whose elaboration cannot be performed statically.
