No, you misunderstand, I simply did not understand what you meant from that

Again, you misunderstand, if you use #if 0, you won't have the compiler 
warnings either.

#if 0
void unusedMethod();

That is correct.

Perhaps, but this can easily be kept local to your tree.

Well, it's not about the superiority of one style over another, but 
uniformity, multiple styles in the same source can be very discouraging to

if you say so :)

good then

I will look at it shortly.  I am done with the code for hiding KisDoc, 
however, I haven't updated my koffice CVS in a while, I'm updating to make 
sure it compiles with the latest, I'm also removing usage of some KDE 
classes/methods that have been deprecated.
