instance b4_table_define in lalr1.cc. This way, we could even factor
C vs. C++ definitions.
+* From lalr1.cc to yacc.c
+** Single stack
+Merging the three stacks in lalr1.cc simplified the code, prompted for
+other improvements and also made it faster (probably because memory
+management is performed once instead of three times). I suggest that
+we do the same in yacc.c.
+
+** yysyntax_error
+In lalr1.cc we invoke it with the translated lookahead (yytoken), and
+yacc.c uses yychar. I don't see why.

* Header guards
From Franc,ois: should we keep the directory part in the CPP guard?
Before releasing, make sure the documentation ("Understanding your
parser") refers to the current `output' format.
