The warning's harmless, but so is preventing it so probably worth doing.
I can't remember if gcc's -Wno-shadow will suppress the warning, it might do.
The best way is to rename either the BasicLock constructor parameter,
or the BasicLock::locked() member function. The obvious choice that
won't break ABI is to rename the constructor parameter to is_locked,
or initially_locked. Same goes for the Lockable constructor
parameter.
