   - GET, GETI, LIST-> and TABLE-> now evaluate symbolic constants instead of
   return associated fonctions in stack;
   - { e } 1 get now returns e and not E. Same fix with infinity and i symbolic
   constants ;
   - GET is fixed and now evaluates names when names are not protected:
   4 'X' sto { X } 1 get returns 4 and not X. Same fix for tables;
   - --enable-native flag is added to configure script;
   - lapack is upgraded to 3.6.0.
   * Thu Nov 26 2015 BERTRAND Joël <rpl@systella.fr> rpl-4.1.23 (RPL/2)

   << 1 'X' sto { X } 'Y' sto 'Y(1)' eval >> returns 1 and
   << 1 'X' sto { 'X' } 'Y' sto 'Y(1)' eval >> only returns 'X'.
   Same bugfix for tables;
   - 4 'X' sto <[ X ]> returns <[ X ]> in both interpreted and compiled mode.
   Before this bugfix, it returned <[ 4 ]> in interpreted mode and <[ X ]>
   in compiled mode.
   * Wed Sep 16 2015 BERTRAND Joël <rpl@systella.fr> rpl-4.1.22 (RPL/2)

   algebraic expressions were able to be directly evaluated);
   - major regression introduced in 4.1.19 is fixed in parser.
   << 1 -> X << exp >> >> returned syntax error;
   - compilation() now returns an error if a definition name contains invalid
   characters instead of BUG();

   q-tree have been written and successfuly tested;
   - EQV intrinsic is added;
   - major bug is fixed in XOR intrinsic (erroneous truth table with integer
   or real arguments);

   * Wed Apr 23 2014 BERTRAND Joël <rpl@systella.fr> rpl-4.1.17 (RPL/2)

   - OpenMotif is patched to correctly detect fontconfig;
   - sqlite and ncurses are patched;
   - rpl.inc is fixed;
   - rpl() now sends arguments to RPL/2 subroutine;
   - rpl() prototype is fixed (rpl_home is an unsigned char * not an unsigned char
   **);
   - GSL is upgraded;
   - major bug is fixed in READ intrinsic (Unix device).
   * Fri Sep 6 2013 BERTRAND Joël <rpl@systella.fr> rpl-4.1.15 (RPL/2)
   - RGDL and RGDR (ragged left and ragged right) are added;
   - major bug is fixed in initialization (segfault). It only occurs when RPL/2
   is built with a forced localization;
   - EXIT regression is fixed.

   - some race conditions have been fixed;
   - sqlite is upgraded;
   - Major regression is fixed in IFERR/END structure;
   - Major regression is fixed in evaluation(). Local variables were exported
   to called definitions.
   * Mon Apr 1 2013 BERTRAND Joël <rpl@systella.fr> rpl-4.1.13 (RPL/2)
   - integer overflows have been fixed (NEG, ABS, minus);
   - global variables can now be recalled from ATEXIT procedure;
   - ATEXIT registered procedure is now executed even if program is stopped by
   SIGINT;
   - minor bug is fixed in TOKENIZE intrinsic instruction. TOKENIZE did not work on
   a copy of input string;
   - major bug (segfault) is fixed in liste_variables(). It only occurs
   when this function is called with shared variables;
   - all internal data are now stored in 64 bits wide integers (even is 32 bits
   ABI is selected);
   - major bug is fixed in recherche_instruction_suivante(). In some
   circumstances, this function can return a spurious error;
   - new NATIVE*(*) data format is added. By default, native*(*) is used
   to write data without precision loss. It can also be used to write
   complex objects like expressions, lists or tables;
   - major bug is fixed in formateur(). When INT64_MIN was pushed into stack,
   internal value was good but RPL/2 was not able to correctly display
   this value. This bug comes from ABS as ABS(INT64_MIN) cannot be represented
   in integer. All abs(), fabs() and labs() present in source code have been
   checked to avoid this kind of bug;
   - unformatted sockets are now usable as unformatted files;
   - BACKSPACE now runs on unformatted file;
   - major bug is fixed in BACKSPACE that didn't check if '"' characters were
   escaped;

   destacked when execution error occurs;
   - major bug is fixed in READ (socket interface);
   - minor bug is fixed in analyse_flux().
   * Wed Feb 27 2013 BERTRAND Joël <rpl@systella.fr> rpl-4.1.12 (RPL/2)

   - CIPHER new intrinsic is added to perform key generation, decryption and
   encryption;
   - CBC-CMAC digest is added;
   - HMAC digest is added;

   routine to keep operating system as clean as possible;

   a signal handler can be called within a special thread and not in the
   calling thread;
   - static variables are now written in a variables tree;
   - major bug is fixed in STO intrinsic. STO returns an error when it has
   to create a global variable if intrinsic none (default) is set.

   - CRITICAL/END structure is added. When program enters in a critical
   section, all other threads of the same process sleep until program leaves
   critical section.
