I don't know what happened in the past week, but all of my build 
logs are filled with this kind of spew:

/dev/shm/tqt3/plugins/designer/libcppeditor.so: undefined symbol: 
_ZN6Editor11eventFilterEP8TQObjectP7TQEvent

Including tqt3.

My build set from a week ago does not have this and I never have 
seen this before in every single module.

What happened?
