That printf lacks format specifiers for stdint.h is a pretty fantastic
bug, yeah.  Almost as fantastic as varying the typedef for XID across
platforms.

So, the XID typedef lives in Xdefs.h, which we can't really change
because it's also included client-side.  But Xdefs.h defines remarkably
little, and we don't actually include it from that many places in the
server.  I'll rework this so we no longer include it, so XID can be
sanely typed in the server (ie, uint32_t).  It'll be like the future.
