KConfigXT generated private members

[Duncan Mac-Vicar P.]

I noticed kconfig_compiler generates private members without a d-pointer 
(Private class). If I would need to expose a generated .h file as public api 
(for plugins) (it already supports adding visibility settings) it will be 
kinda hard to maintain BC when new settings are added.

Is there any reason is was done this way, or adding this feature would be an 
enhancement?
