It was some dsputil stuff. I'm sorry, I didn't write it down.
If someone makes a patch to change it I'd happily test it on a few
different compilers (though I admit I don't even have a gcc 3.3 here
anymore, since it was buggy in other aspects as well).
Are there any other obvious disadvantages to changing it?
