Comment 5 for bug 931500

It's a cast-align error which is something to do with is something to do with how members in a struct are placed in memory. I have not come across one before and neither has agateau or an experienced ARM porter working on Maemo.

It could be worked around by turning off -Werror=cast-align but that might mean a problem appears later

It could be fixed by porting the code to use non-deprecated methods but I don't know if compiz kde plugins are well maintained.

Or it could be dropped from the package, I don't expect compiz kde plugins are much used now that KWin has compositing support.
