teak-llvm/lldb/source/Commands/CommandObjectLog.cpp
Greg Clayton e0d378b334 Fixed the LLDB build so that we can have private types, private enums and 
public types and public enums. This was done to keep the SWIG stuff from
parsing all sorts of enums and types that weren't needed, and allows us to
abstract our API better.
