We don't need anything in this release, but I think it doesn't hurt to just stay up to date. The new version has a new include file, stl.h. To keep things clean and separated, move the imported files to a new sub-directory. This requires a small change in gdb/check-include-guards.py, to be able to ignore the whole new directory.
