You seem not to have gcc 4.* or later, not adding -D_FORTIFY_SOURCE.
That is because 5.28.1 has the following:
case "$gccversion" in
[4567].*) case "$optimize$ccflags" in
Using
sed -i 's/^\(\[4567\)/\18/' Configure
gives me

This still applies to 5.28.2. I guess that distros such as fedora
and Arch have not reported this upstream because they *always* force
their own CFLAGS which include a -DFORTIFY_SOURCE setting.

Is there a reason why we won't add that sed to the book?
Inertia plus we just found out about it.
sed -i 's/67]/6789]/' Configure
ought to do it. I'll do that today.
