I have been reading through the Boost Filesystem library trying to get a feel for syntax. I'm looking at the current version available through sourceforge (1.33.1). I also noticed that the sourceforge version is different than the CVS version. Anyway: file: /libs/fileystem/src/path_posix_windows.cpp function: m_path_append(const std::string&, name_checker) lines: 305 -311 // append '/' if needed if( !empty() #ifdef BOOST_WINDOWS && *(m_path.end()-1) != ':' // QUESTION related to this #endif && *(m_path.end()-1) != '/' ) m_path += '/'; ------------------------------------------------------------- The line in question appears to be a typo and should actually read && *(m_path.end()-1) != '\\' Has this gone past the radar or do my eyes decieve me?
