If you don't disable exception handling, the compiler must treat the
dynamic call in boost::function as potentially throwing. There is no
way around that.
(If you do disable exception handling, boost::function already does
not throw. It still depends on Boost Exception, but only because that
is where the common workarounds for dealing with BOOST_NO_EXCEPTIONS
live; that is, BOOST_NO_EXCEPTIONS is a valid configuration for the
Boost Exception library.)
