GDB produces unnecessary warnings

[Jim Blandy <jimb@cygnus.com>]

I'm not sure how worthwhile this is, since the code that produced the
warnings is now gone from GDB, with David Taylor's change of Mar 31.
But if you think it's interesting, I'll commit it.

	* gdb.c++/derivation.exp ("print g_instance.a", "print
 	g_instance.b", "print g_instance.c"): Fail if the debugger
	produces a warning.  The compiler thinks these expressions are
	fine, so GDB should too.
