This setlocale's declaration is in libintl.h. In the source tree, it's the
file gettext-runtime/intl/libgnuintl.in.h. In its history on the 0.21.x branch,
between 2020-07-27 and 2022-10-10, I see no relevant change. So, in both
versions, the setlocale function comes from gnulib. This is also confirmed
by looking at the .o files in a build:

$ nm ../../gettext-runtime/intl/.libs/setlocale.o | grep ' T '
0000000000000524 T _libintl_newlocale
0000000000000000 T _libintl_setlocale

$ nm ../gnulib-lib/setlocale.o | grep ' T '
0000000000000000 T _rpl_setlocale

$ nm msginit-msginit.o | grep setlocale
                 U _rpl_setlocale

Now, let's look at the history of gnulib/lib/setlocale.c, on the stable-202201
branch, again between 2020-07-27 and 2022-10-10. It hasn't changed at all! And
the most important dependency of this file, gnulib/lib/localename.c, also has
not changed in a way that would be relevant on macOS.

At the point where setlocale (LC_ALL, "") gets called, what are the values of
- getenv ("LC_ALL"),
- getenv ("LC_..") for all other LC_* variables,
- getenv ("LANG") ?
