Downloaded source tarball sets dated May 25 from
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-current/tar_files/src/ , and
unpacked them.

Running the following command line:

./build.sh -m i386 -D ~/src/netbsd-current/destdir -R
~/src/netbsd-current/release -U

After just over 5 minutes it fails with the following error:

Am I doing anything wrong?  (Fwiw, it is gcc "2.96".)
