33
   data models, the traditional 32-bit data model (ILP32) and the
34
   64-bit data model (LP64).  The format of /proc depends on the data
35
   model of the observer (the controlling process, GDB in our case).
36
   The Solaris header files conveniently define PR_MODEL_NATIVE to the
37
   data model of the controlling process.  If its value is
38
   PR_MODEL_LP64, we know that GDB is being compiled as a 64-bit
39
   program.

   process using /proc on Solaris.  */
