This was discussed a few weeks ago in [1], but I'm starting a
new thread so as not to confuse things with the latest patches in
that thread.  The issue is that it seems like it'd be a good idea to
have specific regression testing of whether translation of the
<inttypes.h> PRI* macros works properly, since that is an aspect
of gettext() behavior that didn't use to work everywhere.

I don't know whether the attached will pass on Windows: we might
not be able to assume that "es_ES" is the right LC_MESSAGES
setting to use.  But it works for me on Linux.

  1. Add a regression test to verify that NLS translation works.

  2. Support "j" length modifier in snprintf.c.
