OTOH, some developers define _WIN32_WINNT==0x0602 because they want access to the vista-specific structures and avoid static linking to the vista-specific functions. BOOST_USE_WINAPI_VERSION would be useful for them.
Count me in that group. It requires a bit more discipline and testing (and GetProcAddress) but it's useful to be able to write software that works on one or the other based on runtime detection rather than precompiled expectations. The part where it will get annoying is for libraries with source, which will be unaffected by the user's defines at the time they include Boost, in turn potentially requiring that they compile Boost itself with different options for different targets. (And Boost binaries are already in the multi-GB bracket even for a simple debug+release setup.)
