Hmm, I thought the WARNING prefixes were good.  I think these are similar to

"WARNING: password file \"%s\" is not a plain file\n"

in that something during the connection setup is being ignored.

Otherwise, if you just write something but don't tag it with something 
like warning or error, it's not clear how the user is supposed to 
interpret it.  Is it a progress message, is it something bad, etc.?

It looks like the conventions around the code are mixed.  0600 is clear 
enough that we can keep it.

I don't think this is necessary:

+    errno = 0;
