[BERTRAND Joël]

	Hello,

	I have uploaded a new release with some bugfixes and some new
	features:

	1/ Some minors mistakes have been fixed in some locations;
	2/ An internal system stack corruption has been fixed (ctrl+C + EXIT
	intrinsic);
	3/ DER intrinsic is working with functions;
	4/ TAYLR and MCLRIN (TAYLR in 0) have been added.

	Arguments for TAYLR : 'expression' 'variable' evaluation_point order ;
	Arguments for MCLARIN : 'expression' 'variable' ordre
	(evaluation_point = 0).

	For example:

2: '(TAN(X)*Y+X*3)/ACOSH(SIN(X*5-4))'
1: '(TAN(X)*Y+X*3)/ACOSH(SIN(X*5-4))'
+++X der

2: '(TAN(X)*Y+X*3)/ACOSH(SIN(X*5-4))'
1: '((1+SQ(TAN(X)))*Y+3)/ACOSH(SIN(X*5-4))-((TAN(X)*Y+X*3)*5*COS(X*5-4)*INV(SQRT(SIN(X*5-4)-1)*SQRT(SIN(X*5-4)+1))/SQ(ACOSH(SIN(X*5-4))))'
+++X sin

3: '(TAN(X)*Y+X*3)/ACOSH(SIN(X*5-4))'
2: '((1+SQ(TAN(X)))*Y+3)/ACOSH(SIN(X*5-4))-((TAN(X)*Y+X*3)*5*COS(X*5-4)*INV(SQRT(SIN(X*5-4)-1)*SQRT(SIN(X*5-4)+1))/SQ(ACOSH(SIN(X*5-4))))'
1: 'SIN(X)'
+++X 1 3 taylr

3: '(TAN(X)*Y+X*3)/ACOSH(SIN(X*5-4))'
2: '((1+SQ(TAN(X)))*Y+3)/ACOSH(SIN(X*5-4))-((TAN(X)*Y+X*3)*5*COS(X*5-4)*INV(SQRT(SIN(X*5-4)-1)*SQRT(SIN(X*5-4)+1))/SQ(ACOSH(SIN(X*5-4))))'
1: '0.841470984807897+0.54030230586814*(X-1)+(-0.420735492403948*(X-1)^2)+(-0.090050384311357*(X-1)^3)'
