We should prefer the standard syntax (%lld) over nonstandard ways.
There could just as well be platforms that accept %I64d but warn about
it (as being nonstandard).
If that doesn't work for a specific platform, either adjust the test so
that it checks for warnings, or just manually override the result in
pg_config_os.h.
