You can no longer say 'barber is cutting hair' and 'customer is having hair cut' you have to say 'barber is cutting hair of customer C' and 'customer is having hair cut by barber B'. The problem referenced in the Wikipedia remark is this: just because you have M barbers in the 'barber is cutting hair' state and M customers in the 'customer is having hair cut' state, there's no guarantee that some barber isn't trying to clip more than one customer, or that some customer doesn't have several barbers in his hair. Simply start a Barber thread for each barber in the shop. The code as written will manage any number of barbers without any additional semaphores.
