Create a separate library for MiniCL (a rudimentary OpenCL wrapper to run kernels on multi-core CPU using the default C++ compiler, using Win32 Threads or Posix)
tweak vectormath/vmInclude.h for PS3 platforms
fix warning in btKinematicCharacterController

If you still need a system-wide vectormath, make sure to define USE_SYSTEM_VECTORMATH (in build system)
