So when I mark the code I copied with the source, > it should work, shouldn't it? See the legal prerequisites. As it says, the FSF prefers to hold the copyright on all code contributed to GCC. If you copy somebody else's code you can't assign copyright to the FSF because you don't own the copyright. We could request all the authors of Boost.Filesystem to assign copyright, but I don't want to do that, I want an independent implementation (the Boost implementation doesn't follow exactly the same specification anyway). I'm not interested in simply copying the Boost.Filesystem code into GCC. If you want to use the Boost implementation then just use that, with appropriate preprocessor hackery and namespace aliases.
