C++ testsuite changes

I'm working on it.  Something like this is happening:

  virtfunc.exp calls gdb_test_multiple
  gdb_test_multiple gets the "eof" case
  virtfunc.exp calls gdb_test_multiple with nearly the same pattern
  gdb_test_multiple gets the "eof" case
  virtfunc.exp calls gdb_test_multiple with nearly the same pattern
  gdb_test_multiple gets the "eof" case
  virtfunc.exp calls gdb_test_multiple with nearly the same pattern
  gdb_test_multiple gets the "eof" case
  virtfunc.exp calls gdb_test_multiple with a different pattern
  gdb_test_multiple recovers and gets normal output!

I'll try futzing with the problem pattern and see if that makes the
problem go away.

drow> I suspect we need to do an expect update...

Well, tcl 8.4.5 + expect 5.3.9 + dejagnu 1.4.3 works fine on
hppa2.0w-hp-hpux11.11 (as well as i686-pc-linux-gnu of course).

What would it take to do an expect update?  In particular, what is the
list of hosts that have to be tested with a new version of 'expect'
in order to do an expect update?
