typeck.c (mark_addressable): Never set TREE_USED.

Browse Source 
* typeck.c (mark_addressable): Never set TREE_USED.
        * call.c (build_call): Don't abort on calls to library functions
        that have been declared normally.

        * typeck.c (build_binary_op): Fix grammar in warning.

        * exception.cc (__eh_free): Fix prototype.

        * decl2.c (finish_decl_parsing): Handle TEMPLATE_ID_EXPR.

        * decl.c (pushdecl): Handle seeing an OVERLOAD in
        IDENTIFIER_NAMESPACE_VALUE.
