Both "%lld" and "%I64d" can be used with mingw to print 64 bit integers.
However, modern versions of gcc spit warnings with the former, and not
the latter. However, since "%lld" works, it is chosen by our config
setup since it comes first in the list of formats tried. Therefore, to
keep the compiler happy I proposed to rearrange that so that "%I64d" is
preferred if it's found to work.
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.
I did it that way.
