I'll try this evening. It's taken some time but I believe that the
following change broke my original suggested fix to decl2.c
(import_export_decl):

PR c++/18905
* cp-tree.h (integral_constant_value): Declare.
* call.c (null_ptr_cst_p): Use integral_constant_value, not
decl_constant_value.
(convert_like_real): Likewise.
* class.c (check_bitfield_decl): Likewise.
* cvt.c (ocp_convert): Likewise.
(convert): Remove unnecessary decl_constant_value call.
* decl.c (compute_array_index_type): Use integral_constant_value,
not decl_constant_value.
(build_enumerator): Likewise.
* decl2.c (grokfield): Likewise.
* init.c (decl_constant_value): Simplify.
(integral_constant_value): New.
* pt.c (fold_decl_constant_value): Use integral_constant_value,
remove subsequent check.
(tsubst): Use integral_constant_value, not decl_constant_value.
(tsubst_copy, unify): Likewise.
* typeck.c (decay_conversion): Likewise.
(build_compound_expr): Remove unnecessary decl_constant_value
calls.
(build_static_cast_1, build_reinterpret_cast_1):
(convert_for_assignment): Remove comment about not calling
decl_constant_value.
I know the breakage occurred between 12/16/04 00:00:00 UTC and 12/17/04
00:00:00 UTC. I was going to try your previous changes prior to the point
of the breakage. Let me know if you can see why the above might have
affected the situation.
Dave
