In message <199710220445.AAA22737@bach.mc.com>, you write: 

-> gcc has __builtin_return_address() or something like that.

Which seems to not work.  I've been playing around with the Linux kernel
lately, and it uses the __builtin_return_address() all over the place.
You'd be amazed how little any of the messages utilizing it actually
tell you :-< because it seems to spit out the wrong address.
