the warning is generated from:
/GCC/gcc-live-trunk/gcc/cp/semantics.c:3342
the decl is unused on entry to finish_id_expression () ..
.. and marked as used (on line 3306) ... is that expected?
Otherwise, I'd assume that we could guard line 3342 with say...
if (TREE_USED (decl) && TREE_DEPRECATED (decl))
warn_deprecated_use (decl, NULL_TREE);
dunno..
