Re: Silent test failures when no French, Japanese, Chinese locales installed

Hi Richard,

I cannot reproduce this. Just installed a Fedora 29, configured and
ran a gnulib testdir created through
$ ./gnulib-tool --create-testdir --dir=../testdir-posix --with-tests 
--single-configure `./posix-modules`
and all tests pass, including these that you listed.

Can you provide these infos?

$ yum list --installed | grep glibc-langpack-fr

Expected: empty

$ locale -a | grep ^fr_FR

Expected:
fr_FR
address@hidden
fr_FR.iso88591
address@hidden
fr_FR.utf8

$ grep LOCALE_FR config.status

S["LOCALE_FR_UTF8"]="fr_FR.UTF-8"
S["LOCALE_FR"]="fr_FR"

$ ldd test-btowc

Expected:
        linux-vdso.so.1
        libc.so.6 => /lib64/libc.so.6
        /lib64/ld-linux-x86-64.so.2

$ LC_ALL=fr_FR strace ./test-btowc 1

$ LC_ALL=fr_FR ltrace ./test-btowc 1

And of course the GCC command line options and relevant environment
variables that you used during the configure step.
