Thanks for the heads-up Marek, and sorry for the trouble.  Like I said in the
adjacent reply, the warning is expected (I didn't realize the testsuite would
notice that, though).  I think the right fix is to simply add "-w" to
dg-options, and while we are at it, we should probably change -fvta-toggle to
just -fvta as well (because VTA is active either way, right?).

Andrey?

Thanks.
Alexander
