Hi all,

I've got exactly the same problem that John Klos reported:

Bind 9.3.0 was running fine on NetBSD-1.6.1-macppc.

Bind 9.3.0 is running here fine on NetBSD-2.0_STABLE-i386.
I found a workaround on the debian mailing list:

As a matter of fact, I suppress the "inline" directives for the 
rotate_left() and rotate_right() function in rbt.c and now it works like 
a charm.

I don't know who is the bind9 package maintainer nor if it is the proper 
way to correct the bug but it works.

Sorry for my english. I hope it helps.
