Depending on how portable you want to be, getting the size out of ls -l
will not be as easy as it seems: see the comments in mdate-sh.

You can assume them.  (configure wouldn't work if they didn't exist.)

Sorry for not answering this question (I don't know the answer),
but why test only the size ?  Isn't the contents important too ?
If the file isn't too big I'd ship the expected result and
compare it with `cmp'.  If it's too big you can still compute a
checksum to compare.
