	* gdb.cp/exception.cc: Change <iostream.h> to <iostream>.
	* gdb.cp/exception.exp: Use gdb test, gdb_test_multiple.
	Use gdb_compile.  Remove restriction on gcc.  Add some patterns
	for recent version of gdb.  Delete second half, which was a copy
	of the first half with different build flags.  This test is
	still disabled because it is still not ready for production.

-# This file is part of the gdb testsuite
-
-# Note: These tests are geared to the HP aCC compiler,
-# which has an idiosyncratic way of emitting debug info
-# for exceptions -- it uses a callback mechanism, which
-# is different from the way g++ records exception info
-# for debugging
-
-# The tests are in two parts; the first part deals with
-# statically linked (archive-bound) executables, and the
-# second part repeats those tests with dynamically linked
-# (shared bound) executables.  (In the latter case we use
-# a different mechanism to get the address of the notification
-# hook in the C++ support library.) The tests themselves are
-# the same in both parts.

-# ---------
-# IF YOU CHANGE A TEST IN ONE PART MAKE SURE YOU CHANGE IT
-# --------------------------------------------------------
-# IN THE OTHER PART TOO!

+#
+# The interesting compiler flags are: "aCC +A -Wl,-a-archive" .
