'gn_data' has no member named 'callback_data'

[Magnus Henoch]

I'm trying to compile gnokii 0.6.20 on NetBSD/powerpc.  I run configure
like this:

./configure --with-libical=/usr/local --with-libiconv-prefix=/usr/pkg 
--enable-libusb

But compilation fails with this message:

/bin/ksh ../../libtool --mode=compile gcc -fno-strict-aliasing -g -O2 -Wall 
-Wno-pointer-sign -fvisibility=hidden -I/usr/local/include/ -I../../intl

This is quite surprising to me, as the gn_data struct does indeed have a
member named callback_data.  Any ideas?
