 * Thu Dec 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)  * Mon Nov 21 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.5 (RPL/2)
   - RESTART is added (execve() 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)
   - rplcas/@GIAC@/src/config.h is removed to avoid compilation bug. config.h
   written by configure script was overloaded by src/config.h;
   - lot of compilation warnings have been fixed;
   - lapack and blas have been upgraded;
   - ncurses, sqlite and giac have been upgraded;
   - LCASE, UCASE, POS and SUB now handle escape characters;
   - major bug is fixed in INT (numerical integration was unusable as type
   checking condition was always false);
   - SIZE, CHR and NUM can handle strings with escape characters;
   - 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...);
   - lists, and integer, real and complex numbers can now be written in
   unformatted files;
   - rplawk makefile is fixed to avoid build process bug. Warning, with these
   modifications, sources tree has to be writable.
   * Wed Sep 21 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.3 (RPL/2)
   - Linux port, MacOS X port and xBSD ports are tested and fully fonctionnal;
   - libsigsegv is added;
   - OpenMotif is added;
   - all internal signal handlers are rewritten to avoid POSIX signal usage
   and to be async signal safe;
   - SIGSEGV signal handler is rewritten;
   - SREV intrinsic is added.
   * Tue Aug 9 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.2 (RPL/2)
   - I have fixed a lot of bugs in gpp preprocessor (and sent gpp 3.0 to official
   gpp developer). Now, macros like
   
       #define foo foo bar
   
   is evaluated without recursion. gpp 2.24 crashed on stack overflow.
   - LIMIT is added;
   - Now, undefined values like 'infinity/infinity' are computed. Result is
   undef constant;
   - infinity constant is added.
   * Sun Jul 24 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.1 (RPL/2)
   - VERSION now returns OS type, architecture and ABI;
   - configure script is updated. New flags :
       --with-32bits-abi

   types;
   - interface_cas.cpp now catchs exceptions returned by giac.
   * Fri Jun 24 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.0.prerelease.3 (RPL/2)
   - INT intrinsic now uses RPLCAS to compute symbolic integration;
   - minor bug is fixed in INTRINSIC function. Now, this function gives same
   result with ou without -p switch.
   * Wed Jun 22 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.0.prerelease.2 (RPL/2)
   - memory caching is added to new variable tree.

   * Mon Jun 20 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.0.prerelease.0 (RPL/2)
   - New variable management is written. Please note that -p flag does not work
   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.

   - OLD filetype is fixed;
   - FLOW socket support is added;
   - FLOW sequential files are added;
   - new escape sequence is added to handle flow files (\x + hexadecimal code).
