You 10.6 guys are going to have to join the modern world at some point soon though! Even if I keep on supporting this kind of thing in juce, Apple are beginning to deprecate old functionality - the "official" way to support 10.6 is to build on the latest OS version, but set it for backwards-compatibility.
I know that at a point in the futur you'll stop to support "obsolete" systems. Workaround for C++11 and such must be frustrating and hard to maintain. My only wish would be to git tag JUCE accordingly to that.
