[RPL/2] RPL/2-4.00pre8w

[BERTRAND Joël]

	Hello,

	Last release before hollidays ;-) Some mistakes have been fixed:
- minor bug is fixed in HELP intrinsic. When the last instruction was 
not known, HELP function was pushed in operational stack. HELP did not 
work when there were space on input line;
- MEM does not report static variable sizes;
- STATIC is modified to declare static variables in expression. Warning: 
static variables used in expressions are deleted when evaluation of this 
expression ends;
- --enable-final-run-path is added to configure.in script;
- src/Makefile.am is modified to avoid double compilation process;
- minor bug is fixed in recherche_type(). Don't forget that space
are not significant in algebraic expression:
'12 3+ 12    X' is the same expression than '123+12X';
- --enable-debug is modified. Now, return can be defined to print
on stdout its position in source code (line and function);
- False error (system error) was reported by recherche_type();
- recherche_type() returns syntax error if a list is included in
an algebraic expression.

	I'm working on src/simplification.c (functions that shall be able to 
simplify algebraic expression). Next milestone, when these functions 
will run without any trouble, shall be RPL/2-4.00pre9. After this 
milestone, I have to improve file and socket support and I should 
release final RPL/2-4.00.

	Regards,
