Not correct, POSIX.1-1988 has this 100-char limitation but is was removed with 
POSIX.1-2001.

Star supports POSIX.1-2001 since summer 2001. Star autodetects any supported 
format and allows to select a suitable format in create mode. The default 
format used in create mode is still based on POSIX.1-2001 with extensions.
Today, a major reason for not using a POSIX.1-2001 based archive format as 
default is the exsistence of Sun-tar that is still unable to extract 
POSIX.1-2001 based archives.
