--- Comment #12 from Christophe Lyon <clyon at gcc dot gnu.org> --- Just noticed this in config.log: configure:16789: checking for C locale to use configure:16793: result: generic so yeah, there's "some info" that --enable-clocale=gnu did not have the expected effect :-) I'm not sure printing a warning would be easy to notice.... Anyway, this makes me realized that perhaps we should use --enable-clocale=newlib for our newlib targets in CI....
