I fail to understand how having `64' variants of most of the I/O
functions could be convenient.  What I was suggesting is to have only
one version of each function that uses, say, `scm_off_t' and
`scm_size_t' which both turn out to be 64-bit data types.

It's also unclear to me how this would cause troubles when interacting
(at the _source_ level) with 32-bit libraries.

Thanks,
Ludovic.
