filesystem in CVS differs from 1.30.x ?

Hi all. I'm somewhat confused about how to use filesystem, since it appears that the CVS version differs from 1.30.x. In particular, the following simple snippet suddenly wouldn't compile on 1.30.2 using MSVC 7.1: boost::filesystem::path p("dd"); boost::filesystem::ofstream os("dd"); It works, however, with the current CVS version. In fact, I have failed to compile any variant of the above under 1.30.2. Regards, Anders Moe.
