r17645: gcc 4.1.x has started producing "value computed is not used" warnings
in very annoying ways for talloc_steal. This rather strange looking
cpp approach avoids these warnings. It's really a problem in gcc, but
better to do this than put up with the huge flood of warnings.
(This used to be commit 8236a0ac5e80c30e52fccc0ef41a6c808ea43420)
