Yeah, I do

and I should have probably noted that this is a change of behaviour
so its kind of an RFC, and I didn't think about stabs, so w/ this they
probably require 'set language objective-c' 'set language auto' should
restore the old behaviour

waiting on the testsuite to run, but it looks like gdb.objc/nondebug.exp
is going to require 'set language objective-c'.
