libtds API changes are not documented (well, there are not a separate
document, only ChangeLog). API are documented using Doxygen tool
(however is still in progress)

This functions prototype was changed mainly to support ODBC dsnless and
freetds.conf'less connections. Previous tds_connect always called 
config stuff for reading freetds.conf so this part had been splitted.
TDSCONNECTINFO is the old TDSCONTEXT structure (renamed and added some
fields)

This function prototype changed 3 or 4 time from 0.53 to current CVS...
I hope this is the final prototype.

Simply destlen parameter was unused, so we removed it. Is safe to remove
parameter 6 from your code...

This function is suitable to change in next versions (post 0.61, not in
0.61) for supporting direct binding...

I suggest you enable more warning in your compiler and check for
prototype problems...
