In the release candidate, ct_options() returns CS_FAIL only if the input
parameters were (in its determination) invalid.  Setting/getting options
doesn't *do* anything, doesn't communicate with the server or return cached
values.  It just inspects its inputs and returns CS_TRUE unless it detects a
problem.  

The next version (after 0.61) of FreeTDS will have a rewritten, functional
ct_options() for use with TDS 5.0 (Sybase servers only).  It might include
limited support for Microsoft servers, limited to the extent that
ct_options() can return status information without communicating to the
server.  Version 0.61 will have none of this, because it requires new
functionality in libtds.  

If I had a log file of Mr. Wu's session, perhaps I could patch the rc to
satisfy DBD::Sybase Better support of our Perl folks is an interim goal.
Complete support is the strategy.
