Nice :-)

No. Obviously not. Since Cygwin tar reads and saves the POSIX path 
in the tarball, it is absolutely correctly recreated when unpacked
on the target system even when the links are absolute links, say
/usr/include/foo or alike.

Consider - it's _not_ the *.lnk file which is saved in the tarball
but the attribute to be a symlink. You would be right in case of
using WinZip when creating an archive. But that's unfair because it's
only a native Windows tool...
