He's not. He's using an msys tar from (yet another) fork of the
mingw.org MSYS project -- probably in an attempt to avoid the
"cygwin1.dll is in use" problem.  However, if it's not clear by now:
this is a REALLY BAD idea...

...and that's why.  msys has its own definition of "/usr", doesn't
respect cygwin's mounts OR symlinks, and msys 'tar -x' won't even CREATE
symlinks -- symlink-to-files are faked using hardlinks, and
symlink-to-dirs are faked by creating the directory, and recursively
"symlinking"  (e.g. hardlinks) the contents.

Don't do this.
