I don't remember all the rationale (30 years ago!), but a couple reasons are:

1. How would an array of 0 size elements work, when the pointer past the end is 
the same as the pointer to the start?

2. How would you determine the dimension of an array of 0 size elements?

     sizeof(Array)/sizeof(Array[0])
