Hmm. This problem seems straightforward enough to fix, but what I
don't understand is why we've not seen it already. We do have a
buildfarm animal running on Solaris 11.4 [1], and it's not unhappy.
Are you using any unusual build options or toolchain?

I'm the owner of margay. No idea why it works there.
buildfarm tests and building this beta2 is on the same system.
Using just defaults and --without-icu on buildfarm and beta2 compile.
Best regards,
Marcel

I found it fails after
./configure --prefix /usr/local/16-pgsql --without-icu
but compiles with
./configure --prefix /usr/local/16-pgsql --without-icu --with-openssl

Ah. Further digging shows that:
* On Linux, macOS, and NetBSD (probably all *BSD), <limits.h> is
included by <sys/param.h>, which fe-auth.c includes. So that explains
why we didn't see a problem most places, regardless of compile options.
AFAICT <sys/param.h> is not specified by POSIX, so it's unsurprising
if Solaris has a different idea of what it should expose.
* The openssl headers #include <limits.h> from ossl_typ.h, which is
pulled in indirectly from most other openssl headers. So that's why
margay didn't complain.
So I'm now satisfied that the problem is explained, and I'll go
put in the needful #include. Thanks for the report!

Thanks for the fix. I have just noticed this thread after-the-fact.

[ noses around a bit... ] I see that margay uses --with-gssapi,
could that be the difference? fe-auth.c pulls in a fair amount
more stuff if ENABLE_GSS is set than if it isn't, though I did
not check to see if <limits.h> is in there in particular.
