Symlinks on Windows have a flag that indicates whether the target is a file or a directory. Symlinks of wrong type simply don't work. This even affects core Win32 APIs (e.g. DeleteFile() refuses to delete directory symlinks). However, CreateFile() with FILE_FLAG_BACKUP_SEMANTICS doesn't seem to care. Check the target type by first creating a tentative file symlink, opening it, and checking the type of the resulting handle. If it is a directory, recreate the symlink with the directory flag set. It is possible to create symlinks before the target exists (or in case of symlinks to symlinks: before the target type is known). If this happens, create a tentative file symlink and postpone the directory decision: keep a list of phantom symlinks to be processed whenever a new directory is created in mingw_mkdir(). Limitations: This algorithm may fail if a link target changes from file to directory or vice versa, or if the target directory is created in another process.
