Use the official Subversion client for Windows. The cygwin svn client is
*not* supported by the Subversion team.
And more important: it doesn't use the same working copy format since it
simulates a Linux client - working copies are *not* compatible between

Instead of doing very complicated blocks (which I'm sure took you more
than 5 minutes to configure), you could have saved yourself a lot of
work by simply *reading the manual*:

A script can't do that. At least not without reading undocumented
registry entries and using a table to relate the TSVN versions with
Subversion library version it is linked against.

TSVN is a GUI client. If you need a command line client which outputs to
stdout, use the official SVN client (*not* the cygwin one!).
The TSVN installer has the Subversion library version in its filename.

TSVN is not a wrapper around a command line client. It is linked against
the library and doesn't use the command line client at all.
If you like, you can try a GUI client which wraps around the command
line client (I know there is one, don't remember its name - just Google
for it). But I'm sure it won't work reliably (if you know about unicode,
languages and how to write code, you'll know why).

RapidSVN doesn't wrap around the command line client either. It too is
linked directly to the Subversion library. Which means you'll have the
very same problems.

You're trying to solve your problem from the wrong direction. Instead of
trying to force certain versions of SVN clients, you should instead use
the *right* clients to do the job. As mentioned before: *never, ever*
use the cygwin svn client together with any other svn client on the same
working copy. The Subversion team dropped the compatibility of working
copies between different platforms long ago because it never really
TSVN usually releases a new version a few days after the official
Subversion client gets released. So you won't have compatibility
problems if you use that one. If the working copy format changes in
between versions, there's always a big note on each of the websites
(TSVN and SVN) indicating that.
