Seriously? We require a C99-compliant compiler, which is required to
treat the more compact version identically (all undefined names evaluate
to 0 in the preprocessor), and HACKING doesn't mandate that we spell out
a defined-ness check first. Okay, so configure adds -Wundef to the set
of CFLAGS, but I fail to see why we want -Wundef (that's an
anachronistic warning, only there to help you if you are writing code
portable to K&R).
