It's either a change in gcc or a change in the KDE source (note that the 
errors are coming from the KDE h file, not from PyKDE). You're getting into 
files now that are useful (most of the previous stuff wasn't esp needed for 
most people), and just playing whack-a-mole. It's likely to continue until 
there isn't anything of PyKDE left to compile.

I'll have to upgrade/download and see if I can set up the same environment and 
reproduce the errors you're getting (and then fix them, of course). It's 
going to take a while to accomplish all of that, but I will get back to you.
