Find attached the test failures on NetBSD 9.3 and Solaris 11.4, when I define
_GL_MBSTATE_ZERO_SIZE to a value that is 4 bytes smaller than the working one.
In all three cases, there were
assertion "mbsinit (&iter->state)" failed
failures, which means that mbsinit takes into account more initial bytes than
we expected.
On Solaris 11.4, there were also many test failures of other kinds.
> If the former, what went wrong with the source-code analysis?
On NetBSD, I apparently did not locate the right source code of the mbsinit
function, due to the complexity of the citrus code. And did not want to debug
it, because debugging in libc code without debugging information is often
a waste of time.
On Solaris 11.4, we don't have source code, and it apparently behaves
differently than the OpenSolaris derivatives for which we have source code.

It's needed, namely as lower bound for _GL_MBSTATE_ZERO_SIZE:
0 < _GL_MBSTATE_INIT_SIZE <= _GL_MBSTATE_ZERO_SIZE <= sizeof (mbstate_t).
The test suite failures on NetBSD clearly showed what happens when we ignore
what mbsinit() does.

Strictly speaking, yes. But we have long stopped supporting glibc 2.0 and 2.1
as portability targets. We removed m4/glibc21.m4 in 2020.

We have more than 300 uses of '# if/elif __GLIBC__ >= 2' in lib/*.h, and
haven't received reports about it being a problem. So I guess people are clever
enough to remove these extra-pickiness compiler options when they compile
GNU code.

OK for documentation purposes.
Regarding oddball future platforms, they can write 'unsigned long' instead
of 'unsigned' in their definition of mbstate_t; therefore it does not really
matter whether we write 4 or sizeof (unsigned).
And I won't write
sizeof (((mbstate_t) {0}).__count)
outside of comments, since the less identifiers with double-underscore
we use, the better.

OK, done. Also because it's a proprietary platform and without source
inspection, we cannot really know whether there's one locale encoding that
needs the 32 bytes actually.

OK, done.

The problem with this proposal is that we then have two different functions,
used in various places, and one of them will have at most half of the unit
test coverage than what we have now.
We are already far in the land of using undocumented internals and relying
on accidental facts (such as the order of the fields in the mbstate_t).
Only the unit tests give me a certain trust in what we do. In this situation,
I would not like to bet that a random half of the unit tests will give us
the same reliability.
What would the advantage of mbszerotoc32 be? We care most about glibc platforms.
Whether the compiled code clears 4 bytes or 8 bytes of memory (aligned), will
not make a big difference, because
- in the ASCII case, we have a tight loop without mbstate_t and without any
function call,
- in the non-ASCII case, we have to go through the slow glibc mbrtowc anyway.

Thanks for the ideas. The patch would not have been uncontroversial :)
Here's what I'm committing.
I haven't touched localeinfo.c since the code in there is only used for
initialization (once per program invocation, I guess?), thus not performance
critical.
