	* operations.def: (VEC_ELEM_NUM) Treat user-missing values as
	system-missing.

	* parse.c: (parse_vector_element) Fix order of arguments in call
	to expr_allocate_binary().

Sun Mar  6 17:51:05 2005  Ben Pfaff  <blp@gnu.org>

	* optimize.c: (optimize_tree) Fix optimization bug for x**2.

	* parse.c: (type_coercion_core) Set *node to NULL on failure, as
	indicated by function comment.
	(parse_binary_operators) Always return NULL on type_coercion()
	failure.  Should have been doing this anyway, but bug in
	type_coercion_core() filtered through.
	(parse_add) Fix typo in user message.
	(parse_primary) Understand T_NEG_NUM and T_POS_NUM.

Sun Mar  6 10:47:13 2005  Ben Pfaff  <blp@gnu.org>

	* operations.def: Add VALUE function.

	* parse.c: (parse_function) Need an unary composite node for
	variables in A TO B, not a variable node.  Use
	allocate_unary_variable().
	(parse_primary) Use allocate_unary_variable().
	(allocate_unary_variable) New function.

	* PSPP_expressions.pm: Renamed it back to generate.pl but fixed
	the real problem that was preventing the build from a separate
	directory.  I liked it my way better ;-)

	* parse.c: (expr_parse) Fix parameter type.  Thanks to John
	Darrington <john@darrington.wattle.id.au> for reporting this bug.

	* Makefile.am evaluate.h.pl evaluate.inc.pl operations.h.pl
	  optimize.inc.pl parse.inc.p:  

	  Renamed generate.pl to PSPP_expressions.pm and adjusted *.pl
	  to suit. 

	  Fixed everything so that it can be built from an arbitrary
	  directory.


Mon Feb 28 23:52:21 2005  Ben Pfaff  <blp@gnu.org>

	* New directory.
