Hi Ian,
   thanks for the patch. I have a similar unfinished one so I'll merge
it (I think you'll have to wait new year). Is not enough to fully
support unsigned integers but the conversions stuff is good (to fully
support unsigned you have also to tell Sybase server that you accept
unsigned integers and check if all layers can handle these new types).

Happy New Year to everybody,
  Frediano
