ORBit2-cpp and gcc-3.2

[Armin van der Togt <A vanderTogt its tudelft nl>]

Hi,

I tried to compile the cpp branch of ORBit2 using gcc-3.2, and it didn't
work. The reason is that gcc-3.2 doesn't allow assignment of default
values of function parameters in both the function declaration and the
function definition. Attatched is a patch solving the problem (by
removing the assignments from the function definitions).

Regards,

Armin van der Togt
