/* There is a bug in
* gcc version 2.5.8 (88open OCS/BCS, DG-2.5.8.3, Oct 14 1994)
* as shipped with DGUX 5.4R3.10 that can be bypassed by defining
* DG_GCC_BUG in my code.
* The bug manifests itself by the vaule of a pointer that is
* used only by reference, not having it's value change when it is used
* to check for exiting the loop. Probably caused by there being 2
* copies of the valiable, one in a register and one being an address
* that is passed. */
