It appears the author started with 0.52.  Some of his changes anticipated
ours, and he did some things we still need to do, like better structuring of
the bcp and login data structures.  It's a shame he didn't join the project,
because we could have benefited from his work, and adapted the autoconf
stuff to let subsequent releases slide more readily into his file hierarchy.

As it is, it's very hard to evaluate whether or not his optimizations are
any use to us now.  They probably were at the time, but we've made great
strides with TDS 7.0 since the 0.52 days.  Part of the difficulty is that we
can't generate a diff, because  what he started with antedates our CVS
archive on Source Forge.  For example, the archive cited above includes a
file ncbi_cxx/include/dbapi/driver/ftds/freetds/tdsver.h that corresponds to
a file we don't use anymore (include/tdsver.h).  Our earliest copy defines
VERSION_NO  as "freetds v0.53"; his is v0.52.  

There's also a directory cxx/include/dbapi/driver/ftds8.  It's more recent,
but afaict not based on the 0.60 release, at least not directly.  It
includes many of the same changes plus some of ours.  

To me, it looks like his work is lost to us, unfortunately.  Let's hope the
project progresses in such a way that he finds it worthwhile to contribute
to the main tree instead of maintaining a fork.
