`make test` failed

[miaout17]

I found that unit test failed since de49179.

The error message is:

{"init terminating in do_boot",{{yecc_bug,"1.3",{missing_state_in_action_table,294}},[{elixir_parser,yeccpars2,7},{elixir_parser,yeccpars0,5},{elixir_transform,forms,3},{elixir_transform,parse_and_transform,3},{elixir,parse,3},{elixir,eval,3},{lists,foreach,2},{test_helper,test,0}]}}

510a79a is the last good commit.

Oops, as mentioned in Erlang Forum, I think it might be a bug of Erlang R13.

I will try Erlang R14B later.

[miaout17]

OK, Erlang R14B works. It's really a bug of Erlang R13.

I think the minimum requirement is Erlang R14A, and It's nice to be documented in README.
