Finally I found some time to fix some ODBC issues:
1- prepared statements and multiple recordset
2- conversions to binary

1- issuing a prepared query like "select * from table insert into table
values(...)" return two recordsets:
- select one with correct rows and columns
- insert recordset with 0 columns and correct row count
The behavior is so different from MS one (which return a single
recordset) but is more correct

2- conversions to binary (SQL_C_BINARY) return just wire data (or ODBC
numeric representation for numerics). MS ODBC return output parameters
for VARCHAR in a different way. FreeTDS is consistent and return ALWAYS
binary representation (even for VARCHAR)

These are the first difference from MS ODBC (as Bill state we shouldn't
emulate MS bugs...)
