   * Tue Jan 17 2012 BERTRAND Joël <rpl@systella.fr> rpl-4.1.5 (RPL/2)
   - ncurses, sqlite and openssl have been upgraded;
   - major bug is fixed in ** (integer integer **) when first argument is equal to
   -1;
   - major bug is fixed in signal management. With new signal management, thread or
   process were not signalized anymore by POSIX signals. If a thread or a process
   was sleeping, it was not interrupted;
   - minor bug is fixed in OPEN intrinsic. Now, when a socket is open, its default
   adress is set to 0.0.0.0;
   - new rule is added to main makefile (make debian) to build deb package;
   - new benchmark (Xeon W3520 @ 2.67GHz) :

   - recherche_type() did not convert huge integer in real. Now,
   18446744072742037448 is converted into real as value cannot be stored in
   RPL/2 integer type;
   - WFSOCK is modified to handle unconnected sockets;
   - REGEX is added;
   - RESTART is added (execvp() on main RPL/2 process);
   - copie_objet() now returns same MTX (struct_mutex) even if caller wait for
   a real copy. Now, struct_mutex contains locks owner. On Linux or Solaris (for
   example), it is possible to lock mutex from a thread and unlock the same mutex
   from another thread. On NetBSD, system crashes.
   * Mon Nov 21 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.4 (RPL/2)

   - lapack and blas have been upgraded;
   - ncurses, sqlite and giac have been upgraded;
   - LCASE, UCASE, POS and SUB now handle escape characters;

   checking condition was always false);

   - lot of patches for Android and OS/2;
   - configure.ac is improved to remove operating systems special cases.
   - major bug is fixed in DRWS (SDAT was not used...);

   and all multithread/multitask capabilities have been disabled until this
   new subsystem shall be validated.
   * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
   - major bug is fixed in STD format (1E7 sq prints 1);
   - major bug is fixed in READ intrinsic (socket). This bug was introduced
   by a new feature in glibc.
   * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
   - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
   "ALL" IMPLICIT when it runs in interactive mode;
   - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
   to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
   to use SAVE to manipulate global variables;
   - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
   subroutines;
   - fix major memory access violation in evaluation subroutine. Only occurs
   when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
   - fix major bug in evaluation subroutine. 'X(i)' returns execution error
   when X was a vector or a table.
