I downloaded the tip today and did as I always do:
1. Try to build the introjucer - success!
2. Try to build the demo plug - meh, not so successful. I received the following message:
/Applications/Xcode.app/Contents/Developer/Extras/CoreAudio/AudioUnits/AUPublic/AUCarbonViewBase/AUCarbonViewBase.cpp:263:30: Non-constant-expression cannot be narrowed from type 'short' to 'CGFloat' (aka 'float') in initializer list
It is odd as I have done this a few times in the past month or so and I have never had this type of error (others, sure, but they mostly things in my own code). xCode even provided me with an easy fix, but I did not try it as I don't think I should ever change this file at all.
