The default inheritance is *private*, and gcc-3.4 message is correct
(if somewhat cryptic). 

Here is a more explanatory message from HP aCC:

Error 624: "junk.cc", line 11 # This dynamic_cast will always fail
because class A is an ambiguous or inaccessible base of class B.
       A* pa1 = dynamic_cast<A*>(pb4); // (1)
                                 ^^^         

And another from the EDG front end:

"junk.cc", line 11: error: conversion to inaccessible base class "A" is not
          allowed
     A* pa1 = dynamic_cast<A*>(pb4); // (1)
                               ^
Make the inheritance public, and gcc-3.4 will compile it just fine.
