What can I say, gettext is smart. In gc.c we already have this

die(_("gc is already running on machine '%s' pid %"PRIuMAX" (use
--force if not)"), name, (uintmax_t)pid);

and vi.po shows

#: builtin/gc.c:397
#, c-format
msgid ""
"gc is already running on machine '%s' pid %<PRIuMAX> (use --force if not)"

And translators are expcted to keep "%<PRIuMAX>" in their translated
.po files, and whatever translates .po into .mo knows what
%<PRIuMAX> should be mapped to?

That is surprising.

gettext.info answered me ;-)

    The ‘gettext’ tools and library have special support for these
    ‘<inttypes.h>’ macros.  You can therefore simply write

         printf (gettext ("The amount is %0" PRId64 "\n"), number);

    The PO file will contain the string "The amount is %0<PRId64>\n".  The
    translators will provide a translation containing "%0<PRId64>" as well,
    and at runtime the ‘gettext’ function’s result will contain the
    appropriate constant string, "d" or "ld" or "lld".

       This works only for the predefined ‘<inttypes.h>’ macro...

Nice.
