   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.  */
