[Bug-tar] [GNU tar 1.24] empty dir and option -C

[Denis Excoffier]

Hello list,

If you have an empty dir stored in the tar file and you
extract using -C, you get an error message and the
empty dir is *not* restored.

I tried on Solaris 8 and 10, Cygwin, Darwin and Linux
Ubuntu, all with the same effect.

Details below. Thank you for your help.

Regards.

Denis Excoffier.
