hi, can you give me some comment on the following code in bison
pack_vector:
for (k = 0; ok && k < vector; k++)
if (pos[k] == j)
ok = false;
I believe I understand the pack alg from Aho[1986] and flex. But I don't
understand why it does not work if base[i] == base[j] for some i,j
(I confirmed it with bash-4.0/parse.y, it does not work if I comment these
lines)
Thanks!!
