We had already solved a similar issue one, in the very Automake test suite.
Let me see if I can find the reference ...  Oh wait, no need to, we have
registered the learned lesson in t/README already:

* When writing input for lex, include the following in the definitions
  section:

    %{
    #define YY_NO_UNISTD_H 1
    %}

  to accommodate non-ANSI systems, since GNU flex generates code that
  includes unistd.h otherwise.

And peeking in the Git history, I see you already fixed a similar
problem about an year ago, in commit v1.11-2058-g6f4b08d.

Can you try a fix on those lines?

Thanks,
  Stefano
