Ok, hmm.
Try making the following change to the Makefile:
--- a/Makefile
+++ b/Makefile
@@ -277,7 +277,7 @@ y.tab.o: y.tab.c y.tab.h
$(QUIET_CC)$(CC) -o $@ $(CFLAGS) $(CPPFLAGS) -c $<
y.tab.c: exp/expression-parser.y
- $(QUIET_YACC)$(YACC) --no-lines -d exp/expression-parser.y
+ $(QUIET_YACC)$(YACC) --no-lines -d -b y exp/expression-parser.y
y.tab.h: y.tab.c
(I cut and pasted the above, so it is probably not a well formatted
patch anymore).
That is, add " -b y " into the line for yacc. bison by default
doesn't produce y.tab.c y.tab.h, it produces from xxx.y -> xxx.tab.c
and xxx.tab.h, which makes more sense than what yacc does, but it's
not what the makefile is expecting. The "-b y" tells bison to use "y"
as the output file prefix, just as yacc normally does.
then "make clean" and "make YACC=bison" and see if that works.
