Ahh thanks for pointing that out. In fact, we broke the functionality of `JUCE_USE_CUSTOM_AU3_STANDALONE_APP` with JUCE 5.

I’ve now fixed this on develop and also renamed the macro to `JUCE_USE_CUSTOM_PLUGIN_STANDALONE_APP `. Simply define this to 1 in your `AppConfig.h` (or add it as a custom compiler pre-processor definition) and then use the `START_JUCE_APPLICATION` macro as you would in a normal standalone app.
