This is not correct. Sun's tar archives _have_ better portability than
GNU tar archives. The only program that makes problems is GNU tar
itself.

This is not true too.
PD tar (aka SUG tar) from 1987 _was_ POSIX compliant in 1987 and as
the POSIX draft changed in 1987 implemented a subset of the POSIX standard.
In 1989, SUGtar has been adopted by GNU people and starting from then
additions have been made that _violate_ POSIX.
