Most likely a generic problem. There is some safe casts from 64 to 32 bits
if you have compiled with 32-bit file I/O (32-bit off_t), but these should
all be within the store layer, not elsewhere.

Can you please send a complete list with the contents of the relevant
lines (your linenumbers differ somewhat from the normal sources) so I can
audit which of these are for real and which are just stupid warnings.
