--- Comment #5 from Pedro Alves <palves at redhat dot com> ---
I couldn't reproduce this with current flex master:

 $ flex --version
 flex 2.6.4

Looking at the git log, it sound like it was fixed with this:

    Add more defines in the non-reentrant part.

    Fix the reentrant part; don't "#define yyfoo yyfoo" because it breaks
    code that does #ifndef yywrap ..
