ansi2knr is a really dying (and ugly) feature; when have we last seen
a compiler that does not support C89?  I'm not sure if it's time to
deprecate it yet, but it is definitely not worth putting a lot of effort
into.

That said, I did a review of this patch; please read it and apply it to
other testsuite patches.  I don't think we actually need this particular
patch unless we can find an actual use case from, let's say, the last
four years.  Sorry for letting you do the work.

Cheers,
Ralf

In this test, it is not clear which part makes it xfail.

No new tests with oldish test names, please.  Think of serial numbers
that do not decrease.

A distcheck is not necessary here, brings no extra value AFAICS,
so costs only time.

I'm not just being grumpy here, testsuite slowness is a real problem,
with running time of roughly two days on the MSYS system I have
available to test ATM, we should not be wasting another day just because
we were lazy to check whether a distcheck brings in any additional
value.

whether
ansifying, if you must use the term.

For what it's worth, vim has a good and extensible spell checker, that
can check comments and literals only.  If you use vim anyway, you can
pretty much leave it on all the time (or per filetype, with ftplugin
functionality).

Please, stick to GNU Coding Standards style output.  You keep making up
new kinds of "this output must stick out more from the rest" stuff, and
in different ways each time, that looks incoherent when seen as a whole.
Let's please move away from that in any new patches.  Thanks.
