Indeed, I also had forgotten about that port.

Note though the expose of that feature, on newer systems at least, is very much limited at the moment and I stand by my statement that mixing multiple c++ runtimes, unless done very very carefully, is a recipe for problems. So expanding the usage of that option to many more ports should be done carefully.
