When I set TreatWarningsAsErrors to false and AjaxMinTask issues a warning output file is not generated.

Yup, I can repro. That's pretty weird. I'll step into the code and see what's going on. That should definitely be creating the output file.
On a side-note, there's another bug: the lack of an identifier for your function declaration should be an ERROR, not a WARNING. Might be related.
