lib/db/sqlp/yac.y appears to be using non-standard syntax (recent
versions of bison appear to be less forgiving than older versions).

I suggest replacing the line:

	%type <node>	y_comparison, y_condition, y_attr, y_attr2, y_name, y_cnam

with multiple lines:

	%type <node>	y_comparison
	%type <node>	y_condition
	%type <node>	y_attr
	%type <node>	y_attr2
	%type <node>	y_name
	%type <node>	y_cnam

[AFAIK, simply removing the commas should work, but one line per
symbol is more clear.]

Try removing those lines from include/sqlp.h; if that causes other
things to break, then either yac.y/lex.l or sqlp.h (and code which
uses it) should use other names for AND/OR/NOT.
