The change for tds_types.h is not necessary, the invalid constant is
actually 0. Also tds_types.h is auto generated from misc/types.cvs.
The change in include/sybdb.h is also in my patches to support these
types (with new bindings) in dblib.

So... please grab the last snapshot and try again, should work!

Actually there is no automatic tests for freebcp and datacopy (but the
base functions they use are tested).
