A warning would be fine, but I would suggest waiting until someone 
reports an actual problem.  My guess is that no one running Cygwin 1.5 
will ever try to build the emacs trunk.  But if someone does try and 
runs into problems, we can take the appropriate action.  If you 
disagree, I have no objection to inserting a warning now.
