Ok, we'll see. I'd rather test it a little more, though. The extra debugging 
info
adds considerable overhead (I just made it at least execute loops in constant
space, but tail-calls are not really tail-calls), so this has to be optional.
But if it works well enough, we can add it to the base distribution.

I should add here that Peter Keller repeatedly tried to convince me of
writing a real debugger for Chicken that can handle compiled code as well.
Unfortunately, I can't currently figure out how to implement this (efficiently
and portably).

[Peter, if you are reading this: I haven't forgotten about it, but the
changes needed for such a thing are substantial, and the complete change
of the ABI is something that I'm _very_ reluctant to do. ;-) ]
