I'll look at this closer, but the domains are different enough that I'm not sure there's anything that carries over. As for conditional compilation... the Boost.Filesystem stuff has no need for this, while Boost.Threads has a very definate need. > BTW I prefer having the same set of methods, some of them returning default > values for platform without the support for the underline concept. > Sometimes this could not be possible.

Not all platforms will support this, and if they don't a stub that returns an error or throws an exception is doing a great disservice to the developer, since he should know at compile time that this platform can't handle this, since there's nothing he can do at run time to compensate for the lack.
