cxxflags is so called "free" feature -- which is feature which value is not
interpreted. Such features are not propagated to dependencies, for various
reasons. So, you have to use something like:
Boost-Build list run by bdawes at acm.org, david.abrahams at rcn.com, gregod at cs.rpi.edu, cpdaniel at pacbell.net, john at johnmaddock.co.uk
