Considering that we IMHO want to support unformatted sequential records > 2 GB
on 64-bit targets without the user having to explicitly specify RECL= when
opening, I'd suggest making DEFAULT_RECL match huge(0_C_SIZE_T).
The downside is then that if the user inquires for RECL on a 64-bit target
where the RECL= variable is a 32-bit integer, we'll have to generate an error,
per Steve Lionel's comments.
Wrt. the signed vs. unsigned issue, POSIX specifies that off_t must be a signed
type, so all file offset calculations (including record size stuff) should be
done in signed arithmetic. Now, gfc_offset is a typedef for off_t (or the
equivalent type on mingw), so AFAICS we should be ok.
