My quick reaction is that in theory, each program is written in a
specific language family member (LFM, that I'd call a "language" but
others disagree), such as C89 or C89-with-gnu-stuff.

Additionally, compilers support multiple LFMs, and unhelpfully default
to newer ones, rater than enforcing that programs in newfangled LFMs
have to pass --std.

So if make that we have is documented to build with gnu89, we should
just set --std=gnu89 always.

Or is it c99-almost, and this is a kludge?  What is gcc14 defaulting to
for a c std?  Is it really anything newer than c99?
