-----------------------------------------------

It turns out that is_ai_simple_military can be computed before the
game starts. The patch does this and replaces the calls with a new
iterate. Another 2.2% speedup.

  "The primary purpose of the DATA statement is to give names to
   constants; instead of referring to pi as 3.141592653589793 at every
   appearance, the variable PI can be given that value with a DATA
   statement and used instead of the longer form of the constant. This
   also simplifies modifying the program, should the value of pi
   change."
