    Release Notes: This is a bugfix release. All users should upgrade as some major bugs have been fixed in tools and RPL/2 itself. Semaphores have been removed from s_signaux, as POSIX doesn't assure that semaphores are synchronized between address spaces without msync(). All tools have been upgraded (SQLite, OpenSSL, gnuplot, LAPACK; GIAC, units). Use of uninitialized variables is avoided in FORALL. A major bug is fixed in both FOR and FORALL (a segmentation fault if both instructions are not followed by a name).
