Right, PostgreSQL doesn't compile cleanly with the "sign-compare"
warning. There have been a few threads about that, and someone might
want to think harder about it, but it's a different topic unrelated to
<stdint.h>.

It seems my v1 patch's configure probe for INT64_FORMAT was broken.
In the v2 patch I tried not doing that probe at all, and instead
inviting <inttypes.h> into our world (that's the standardised way to
produce format strings, which has the slight complication that we are
intercepting printf calls...). I suspect that'll work better for you.
