Yes, needing 8421f6bce and 605062227 was, perhaps, surprising, but
reasonable. Unlike breaking floating point constants in the source code.
But, I guess, you're right and, since it does look like a Perl bug,
we'll have to work around that in all places where we use floating-point
constants in Perl code, which are surprisingly few.

Indeed, check-world seems to run fine on my machine and on the bf as well.
Grepping and browsing through, I've only found three spots with \d\.\d
directly in Perl code as a float, only one of them needs correction.
1. src/test/perl/PostgreSQL/Test/Kerberos.pm in master
src/test/kerberos/t/001_auth.pl in REL_16_STABLE
> if ($krb5_version >= 1.15)
I guess adding use locale ':numeric' would be easiest workaround here.
Alternatively, we could also split version into krb5_major_version and
krb5_minor_version while parsing krb5-config --version's output above,
but I don't think that's warranted. So I suggest something along the
lines of 0001-use-numeric-locale-in-kerberos-test-rel16.patch and
*-master.patch (attached, REL_16 and master need this change in
different places).
I did verify by providing fake 'krb5-config' that before the fix, with
LANG=ru_RU.UTF-8 and Perl 5.38.2 and with, say, krb5 "version" 1.13 it
would still add the "listen" lines to kdc.conf by mistake (presumably,
confusing some versions of kerberos).
2 and 3. contrib/intarray/bench/create_test.pl

PostgreSQL::Test::Utils is not used there, so it's OK, no change needed.
I did not find any other float constants in .pl/.pm files in master (I
could have missed something).

Yep. I will try to report this to Perl community later.
