+   code, but on some machines (RS6000, HPPA, others?) it may fail when
+   called directly by GDB.
+
+   In a nutshell, it's not possible for GDB to determine when the address
+   of a function or the address of the function's stub/trampoline should
+   be passed.
+
+   So, to avoid GDB lossage in the common case, we perform calls through the
+   various function pointers and compare the return values.  For the HPPA
+   at least, this allows the common case to work.
+
+   If one wants to try something more complicated, pass the address of
+   a function accepting a "double" as one of its first 4 arguments.  Call
+   that function indirectly through the function pointer.  This would fail
+   on the HPPA.  */
