The non-free (but open source) unrar lib has this license:
4. Legal stuff
Unrar source may be used in any software to handle RAR archives
without limitations free of charge, but cannot be used to re-create
the RAR compression algorithm, which is proprietary. Distribution
of modified Unrar source in separate form or as a part of other
software is permitted, provided that it is clearly stated in
the documentation and source comments that the code may not be used
to develop a RAR (WinRAR) compatible archiver.
As I understand, it does not limit the possibility of using it as a
reference for a free implementation of the *de*compression algorithm.
As an example, the zip and unzip programs come from different source
packages. INAL, but I see no problem in creating a GNU unrar program,
as long as the code from unrarsrc is not used, just the concepts.
