That depends on the granularity of the conditional block (something
between conditionalizing a single token and including an entire header).
What works best depends on the specific context.
In Boost.Python there aren't that many places in need of
conditionalizing. Most code is so generic it doesn't even know or care
whether it's passing shared pointers around.
