SQL_ATTR_ROWS_FETCHED_PTR support was added in CVS version, not in 0.61,
so I think iODBC emulate it.
Perhaps unixODBC do not emulate it (and it's a correct behavior).
Also do not use 4.2 version. This version do not support some features
and shouldn't be used anymore (the only exeption is for dblib for a
compatibility issue related to RPC).
