Yes. errmsg() strings are captured for translation. If they contain
platform-dependent substrings, that's a problem, because only one variant
will get captured. And INT64_FORMAT is platform-dependent.
We have of late decided that it's safe to use %lld (or %llu) to format
int64s everywhere, but you then have to cast the printf argument to
match that explicitly. See commit 6a1cd8b92 for precedent.
