Thanks. I will keep an eye on it.

With the patch, configure runs to a successful completion. make and make install also succeed.

I have one other question with regard to configure. Here's what I'm using at the moment:
./configure \
	--prefix=/usr \
	--sysconfdir=/etc/bind10 \
	--localstatedir=/var \
	'CFLAGS=-O2 -fno-strict-aliasing' \
	'LDFLAGS=-Wl,-Bsymbolic-functions'

The CFLAGS and LDFLAGS parameters are what the Ubuntu package maintainers use with their bind9 packages. Are any of these necessary or helpful for building bind10?

Thanks again for your help. Jeff.
