I've made those changes, but (using 0.82rc2, which is probably not quite 
the latest) I get errors with CS_BIGINT not defined (and I can't test 
for that, as that's a typedef, not a #define in Sybase's implementation).

So it looks to me like FreeTDS's OC implementation has a small problem 
in that respect (or at least had in the version I have here).
