+   data models, the traditional 32-bit data model (ILP32) and the
+   64-bit data model (LP64).  The format of /proc depends on the data
+   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
+   program.
+
+   Note that a 32-bit GDB won't be able to debug a 64-bit target
+   process using /proc on Solaris.  */
