I'm trying to compile RC2 and have the same error as the original poster.  This
patch doesn't seem to be able to be automatically applied to frame.h in RC2, and
I wasn't able to figure out what the changes need to be.  This patch does work
great for me on beta40; I checked today and was able to compile with no
problems.  In frame.h, what in beta40 we had:

#define DECLARE_THREAD_LOCAL_PTR(ptrType, ptrName)
Pthread_Thread_Local_Pointer<ptrType> ptrName;
#else
#efine DECLARE_THREAD_LOCAL_PTR(ptrType, ptrName)       __thread ptrType
*ptrName;
#endif

but in RC2 we now have:

#ifndef DECLARE_THREAD_LOCAL_PTR
#define DECLARE_THREAD_LOCAL_PTR(ptrType, ptrName)
boost::thread_specific_ptr<ptrType> ptrName
#define IMPLEMENT_THREAD_LOCAL_PTR(ptrType, ptrName, ptrCleanup)
boost::thread_specific_ptr<ptrType> ptrName(ptrCleanup)
#define GET_THREAD_LOCAL_PTR(ptrName)
(ptrName.get())
#define SET_THREAD_LOCAL_PTR(ptrName, ptrValue)
(ptrName.reset(ptrValue))
#endif

I'm not knowledgable enough to know how to modify the patch for RC2.  Can
someone help?  I'm trying to compile on Mac OS X 10.6.6 using the llvm-gcc
compiler.

Thanks for any help you can provide,

Adam
