In accordance with the method of invention, a class hierarchy is derived which maintains release-to-release binary compatibility. Leftmost classes of the class hierarchy are ordered in top down order with a most derived class at the bottom. Direct virtual classes are ordered from left to right with the leftmost class in declaration order at the top. Leftmost classes are independently grown downward and direct virtual classes are independently grown upward.
