Actually I am, but I overlooked that.

By the way, some of those compilers will not eliminate the recursion if you
don't turn on the optimization flag. The programmer is making the correct
execution of the code depend on his expectation that the tail recursion will be
eliminated by the compiler, instead of eliminating it himself. A large loop
will blow the stack without the presence optimization, or use an inordinate
amount of memory.
