There may not be a problem. gcc/g++ 4.0 is more eager (too eager, in my
opinion) to warn about problems in code paths for which its flow
analysis can't determine reachability. If a code path is really
unreachable but gcc doesn't think so, it should be possible to suppress
such warnings by adding an assertion such as assert(!"This can't
happen") (assuming that NDEBUG is not used).

You seem to have the wrong version of the Boost source. That function is
in time_parsing.hpp, not time_duration.hpp, in version 1.33. You could
install the libboost-date-time-dev package from sid instead of compiling
it yourself.
