kde 3.4 & C++ ABI transition

[Arnaud Battistella <arnaudbattistella@gmail.com>]

Hi, I saw this new threat on kde 3.4 and I had a quick related question. 
 I understood that upgrading to kde 3.4 from Alioth should be safe but 
I was wondering if I could have some issues once kde 3.4 will enter 
unstable.
Thanks for your help,
Arnaud
