1) I have noticed the failures for the obj-c++ testsuite:

FAIL: obj-c++.dg/attributes/method-noreturn-1.mm -fgnu-runtime  (test for
warnings, line 21)
FAIL: obj-c++.dg/attributes/method-noreturn-1.mm -fgnu-runtime  (test for
warnings, line 25)
FAIL: obj-c++.dg/attributes/method-noreturn-1.mm -fgnu-runtime (test for excess
errors)
FAIL: obj-c++.dg/attributes/method-noreturn-1.mm -fnext-runtime  (test for
warnings, line 21)
FAIL: obj-c++.dg/attributes/method-noreturn-1.mm -fnext-runtime  (test for
warnings, line 25)
FAIL: obj-c++.dg/attributes/method-noreturn-1.mm -fnext-runtime (test for
excess errors)

2) I have applyied the patch of revision 169927 for its sibling test for the
objc testsuite: objc.dg/attributes/method-noreturn-1.m

3) I have tested it.

4) I have posted the patch to this pr before leaving my office for the day.

5) I have been busy with real life up to now;-)

So any comment for obj-c++.dg/attributes/method-noreturn-1.mm applies as well
to objc.dg/attributes/method-noreturn-1.m. Last point I don't have any commit
right.
