Hi everyone,

I've fixed the text and image datatype handling for TDS 7.0 and its in

One little thing I noticed, under TDS 4.2 @@textsize defaults to 4096,
under 7.0 it is 2gig.  This crashes sqsh which tries to allocate maxlength
+ 1 (a negative using CS_INT), probably crashes some other stuff as well.
So, if you are using text types under 7.0, I'd recommend doing a 'set
textsize' first.  This is BTW dependant on the protocol version,
using 4.2 against a MS SQL 7 server still has textsize at 4096.
