Re: C++ testsuite changes

[mec.gnu@mindspring.com (Michael Elizabeth Chastain)]

Okay, this fixes the ERROR/UNRESOLVED problem on my system

"(void|)" alternative with more alternatives at a higher level.

Mark, can you try this?

	* gdb.cp/virtfunc.exp: Modify some patterns to avoid a
	mysterious bug with sourceware version of expect.
