Hi,

I was running into a problem due to FreeTDS not supporting Sybase's unsigned 
integer types (SYBUINT1/2/4/8). It was manifested as cs_convert failing to 
convert other types (such as SYBNUMERIC) to those unsigned types, and 
reporting:

cs_convert: cslib user api layer: external error: Conversion between 108 and 
-1 datatypes is not supported

I have attached a patch that addresses the issue for me, in the hope that it 
might be useful for others. I tried to make it fairly complete in the areas 
of the code that I touched, but I was only following my nose so have quite 
likely overlooked other parts of the code (including test cases) that are 
also lacking SYBUINTn support. YMMV etc.

Ian
