There is another potential gotcha with the later boost versions. We're
using boosts unordered_map, etc. and with gcc at least the latest
versions of boost::unordered_map only build in c++11 mode I think so I
don't think it'll be possible to upgrade our internal boost (unless
patched to revert to an older version of boost::unordered_map) ?

Will be obvious at buildtime with lots of errors that suggest that copy
ctors (or was it assignment operators) are non const or some such.
