Right, I think offt from sys/types.h is a good candidate. It's signed, on x86-32 has 32 bits, on x86-64 has 64 bits.
NO!
-- Data Type: off_t
This is an arithmetic data type used to represent file sizes. In
the GNU system, this is equivalent to fpos_t' or long int'.
If the source is compiled with `_FILE_OFFSET_BITS == 64' this type
is transparently replaced by `off64_t'.[...]
