I don't think it's so easy to write an installer program or enable
registration of freetds.dll with regsrv32 (although this should register
only COM classes :) )

Usually we use diff -u. However you can send diff in what format you
wants (or just send modified/added files if you prefer). Patch will be
updated and applied to CVS HEAD (what we call it 0.63). We maintain 0.62
only for fixes, not improvements (our time resources are very limited).

Send them to me if you prefer or post in sourceforge project (don't
forget to check the box :) ).

My suggestion is "forget servername" all users want real server name so
use server. Is useful only if you use other libraries (ctlib/dblib).
Also under windows freetds.conf is in c:\ ... not that fine.. "Address"
was added for compatibility with MS ODBC and to solve DNS resolve
problems (/etc/hosts is not editable to everyone...). I think there
should be an "Advanced" button for "Address" and (if you require it)
"Servername".

See James reply.
