Got a problem compiling the new GCC. Here is the output I get:

What the heck is unwind?

Can anyone tell me where "unwind" come from? Is it from my use flags, or does it always get compiled?

No replies at all?

unwind is part of GCC, there are discussion about it making problems on IA64 at the gcc mailing list. I don't know what it is exactly though.

Well, it looks like the update has been re-masked on my last sync, so my world update can succeed now. We'll see what happens when it is unmasked again.
