Btw, I did write a PR for being able to handle such arbitrary NaN literals without warnings, but it was chosen not to merge that in, if I recall correctly, the thinking was that it would be an impossible scenario to occur. The related PR was here: https://github.com/kripken/emscripten-fastcomp/pull/116 which was amended to demote the handling to the warning you are seeing. It would be interesting to hear what kind of code pattern does cause this.
