Right.  Another option is to pull in and "llvm-ize" libraries that are  
really useful.  For example, llvm/ADT/OwningPtr.h is a simple smart  
pointer that is very similar to boost and other standard libraries.

There are several goals here, but the goal is to keep the code simple,  
self contained, and portable across a wide variety of compilers.  TR1  
may be getting widespread enough that it might be reasonable to start  
depending on it.
