Hi Guys,
 Find attached CMakeVMMaker-LucFabresse.143.
What I did:
 - Add hook CPlatformConfig>>printExtraHeader: to be able to change compiler in Config
 - add config CogMTCocoaIOSGCC42Config which forces gcc-4.2 (useful on OSX with XCode 4.2 that now uses llvm backend)
 - fix StackCocoaIOSCLANGConfig to use compiler clang 

 It seems to work for me ;-)
 Perhaps it could be added in VMMaker repo?
