Right. I had in mind that there just was a patch in the past.

Right. This could break a lot of apps perhaps. But on the other side
chars (readable characters) should always be char, right? Or have I
missed some architecture depending things?

So THREADINFO td_name should also be a char, right?

One should check every change of this patch carefully and should think
about adding the patch in the future. Casting is not a realy nice way.

For right now I changed back to gcc 3.3.6

Ole Reinhardt
