The code im working on is part of FreeBSD and uses FreeBSD's
infrastructure for building. I can avoid the warning by defining
WFORMAT to be 0 but I don't know how to add -fno-builtin-strftime
except directly into CFLAGS.

I don't think the original author (John Hubbard) is around anymore so
the question is - should I just remove WFPORMAT from this Makefile?
