I don't understand why it fails in the fourth case. The comparison it seems to
complain about is generated via
return build2 (NE_EXPR, boolean_type_node, decl,
fold_convert (TREE_TYPE (decl), null_pointer_node));
(trans-expr.c:141) which looks like it gets the types right. Replacing the
call to fold_convert with an equivalent call to build_int_cst doesn't help
either, BTW.
