I only had a quick look at the parser, and one thing that strikes me is:

+Patterns:
+	/* EMPTY */
+	| Patterns Pattern
+	| Pattern
+	;
+
+Pattern:
+		C_INCLUDE include_object pattern { include_item(priv, $2, $3); }

It seems confusing to mix Pattern(s) (the rules) and pattern (the token).
Maybe instead using Include(s) or Item(s) on the bison side, and/or
name_pattern on the lexer side?
