I'd rather keep them but disable with #if 0, if it's only about the
minor compiler warnings.
The whole code is a result of reverse engineering and those dead code
are simply there just because of lack of testing. Removing makes it
impossible for retesting (if any).
thanks,

Actually you can easily recover the code from git history.
Anyway, it's all your choice.
