In another newsgroup the question came up to what degree the
GNU "C" compilers can handle optimization of recursions like
fib() or ack(), i.e. cascading ones. Somebody here may know?

Can we expect that (with the higher optimization levels) the
exponential complexity from cascaded recursion gets linearized?
