i don't know what's wrong. s-purex.o exports such symbols.
linker bug?

Most likely a bug in the bootstrap compiler (PR ada/27936).  Try with 3.4.x.

Subject: Bug 30684

Author: ebotcazou
Date: Tue Feb 20 23:54:16 2007
New Revision: 122181

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=122181
Log:
        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.

You need to upgrade your 4.1.x compiler.
