Thanks for your assessment of the problem: indeed, I can tell you for
sure that (b) it's true and, as reported by Kriang, the patches are
rather simple (but the details of this judgement are up to you, of
course). I'm not 100% sure about (a) but Michael can tell you better:
AFAIK, KDE Kopete used to compile and work well pre-4.0.
