Isnt there a dynamic way of checking support for hardware break/watch points. May be query hardware debug registers and if it fails just disable hardware breakpoints for that thread.
The code relies on `struct` members that are only present with this version. I'd like to avoid copying implementation details like that into the code.

I generally leave naming decisions to @labath ;-).
