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.
