  I haven't checked, but would bet WinRAR and 7-Zip don't accurately recreate
the posix permissions when they unpack a *nix tarball.  They probably don't
unpack device nodes right either.  They can probably get softlinks right but I
haven't tested that either.

  Rather than play guessing games about which gui-based unpackers will do a
good job of unpacking something into a Cygwin environment and have to
repeatedly re-solve the problems they may cause every time someone says "Oh,
well you said not to use WinZip, so I used WinRAR (or whatever) instead", I
just err on the side of caution and simply advise: for unpacking stuff into a
Cygwin environment, always use a Cygwin-aware tool.

    cheers,
