Bingo!  

$ mkdir d
$ md5 d
MD5 (d) = 45dceb078703c7df15a46c65ee86f702
$ touch d/t
$ md5 d
MD5 (d) = 945ddd2c59b0fdb0421df0fe823ba177
$ ls > d/t
$ md5 d
MD5 (d) = 945ddd2c59b0fdb0421df0fe823ba177

Craig, thanks a heap!  You can add this to your list of contributions to
the FreeTDS project.  All this time I've been wondering what was wrong. 
The *assumption* that MD5 worked on the tree, I never questioned.  Argh!  

The way home is now short.  I think "find freetds -ls" | md5 will work
fine.  Or, for that matter, "md5 freetds/ChangeLog".

Generating the tarball doesn't quite work, unless done twice, because the
tarball has a version number derived from the date.

No.  Subversion uses a repository-wide version number, though, and
Frediano and I both want to switch.  That's a future possibility: instead
of ".dev.{date}" the development version could be ".svn.{revision}".

You might not be aware the distribution tarballs are generated on a NetBSD
system.  

Thanks also for the patch.  Might as well ship the gifs, too.
