Dirk found out meanwhile that's this is a gcc 3.3 regression and it's most likely
to be fixed for 3.3.2 (btw: the 3.3 prerelease on SuSE 8.2 doesn't show the
problem either). It just doesn't help you now I guess ;(

I thought gcc supresses warnings from system headers. Not any more?

If you have an idea how to check for these in another way, I'm glad to hear.
