I have code that looks like this

{
// stuff

When I call [response statusCode] in the code above, CodeWarrior warns
that "receiver cannot handle this message." Obviously this was taken
care of on the previous line, but I can see how a compiler might not
understand this :) How can I placate the compiler and silence the
warning (other than disabling warnings)?
Use GCC?
Seriously, Codewarrior's ObjC support kind of stinks, and I won't even
get into its PPC code generation. (*retch*)
If you're being forced to use Codewarrior, though, I'd advise getting
rid of the respondsToSelector (as it's really just a waste of time -
assuming that this is a delegate method, the NSURLResponse will
_always_ respond to statusCode) and adding something along the lines
of:
#warning Please ignore the following warning.
