My impression was Doug was passing on a warning about the continued used
of mktemp(3) rather than the continued use of ASCII.

Given -Wall -Wextra still doesn't enable all warnings, I expect there's
a bunch of complaints that could be addressed by explicitly choosing
really-extra ones with recent compiler versions, e.g. gcc 8.2.1, and
clang 7.0.1.
