+ data models, the traditional 32-bit data model (ILP32) and the

+ model of the observer (the controlling process, GDB in our case).
+ The Solaris header files conveniently define PR_MODEL_NATIVE to the
+ data model of the controlling process. If its value is
+ PR_MODEL_LP64, we know that GDB is being compiled as a 64-bit
