When I compile with this ./Configure switch:
-Accflags="-DNO_LOCALE_NUMERIC"
... compilation fails on both OpenBSD and FreeBSD (using clang10 on both OSes) at this point:
$ sh ./Configure -des -Dusedevel -Accflags="-DNO_LOCALE_NUMERIC" && make miniperl | tee $P5P_DIR/make-output/`extract-sha`.openbsd.clang10.unthreaded.onlynolocalenumeric.makeminiperl.output.txt

The above was observed on OpenBSD-6.9 at commit 7b92fe4. I have reproduced it on FreeBSD-12 as well. I originally spotted this problem in this smoke-test report: https://perl5.test-smoke.org/report/5019634. I customarily smoke-test on OpenBSD with -Accflags="-DNO_LOCALE_NUMERIC -DNO_LOCALE_COLLATE" because that is closer to the "system perl" configuration options used by @afresh1.
On an older Linux installation, with the same configuration I get:
$ uname -mrs

locale.c: Use low level macros at low level
Implementing Perl_setlocale, we can safely use the internal macros that
the public ones expand to call, without the overhead those public macros
impose (which they do to be more immune from improper calls from outside
code).
@khwilliamson, can you take a look?
