I just committed the patch to change XLogRecPtr into a 64-bit constant, 
and I did this in the patch:

#define XLogSegmentsPerXLogId  (0x100000000LL / XLOG_SEG_SIZE)

But I started to wonder, is that LL representation the preferred way to 
define 64-bit integer constants? I thought it is, but now that I grep 
around, I don't see any constants like that in the source tree.
