   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;

   << 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.

   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();

   - 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)

   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;
