From Stephan Huber, "attached you’ll find a bunch of fixes + enhancements for iOS and OS X based on current trunk. I incorporated + tested the submission from Colin Cochran, so his submission is not needed anymore.

* fixed a bug with multi-touch and touch-id-generation on iOS and OS X. (will fix a bug reported by Colin Cochran, without ditching the existing logic)
* removed unnecessary warning-flagss when generating xcode-projects via cmake, will enable the usage of OSG_AGGRESSIVE_WARNING_FLAGS
* added support for 10.9 (OS X)
* new cmake-variable: IPHONE_VERSION_MIN, this will set the deployment-target (previously hard-coded) If you set the IPHONE_VERSION_MIN to something like 7.0 osg gets compiled also for 64bit (amd64)
* cmake defaults now to the clang compiler if IPHONE_VERSION_MIN > 4.2
* cmake now sets some xcode-settings so the compiler uses the c++98-standard (clang defaults to c++11, w/o this I got a lot of linking errors)
* removed include-dir for avfoundation-plugin as not needed on OSX/IOS.
* enhanced the ios-example, will now show multitouch-information on a hud (similar to the  osgmultitouch-example), and more importantly, will compile + link out of the box
* small enhancements for the osc-device-plugin (send only one msg for MOVE/DRAG, even if multiple msgs/event is enabled)
* better memory-handling for the zeroconf-plugin
* fixed a possible bug in the rest-http-plugin when receiving mouse-events.
* incorporated a fix from Colin Cochran "forwarded touch events are not transformed into the GL UIView“
