//  This file defines a stack dumping function that can be used for debugging.
//  It is called whenever the DUMP built-in word is used in the Stacker source.
//  It has no effect on the stack (other than to print it).
//
//  The real reason this is here is to test LLVM's ability to link with
//  separately compiled software.
