- auto-generate config.h

- suppress all exit(EXIT_FAILURE), FIXME, ...

- no chmod/chown(uid,gid) for TAR

- Use a more portable "String.h"

- UTF16 : try to test with Complex Unicode filenames

- KNOWN BUGS

  - date ('x' and 'l')
  7za l archive.7z  (7za l archive.tar)
  and 7za x archive.7z and then "ls -l"
  => not the same date

  - date (format arj/rar/chm)

  - absolute path ?

- zip format : better support of symbolic links
