Freetds perl limitation

Currently I see following limitation in perl dbd with freetds
 
1. Can not prepare more than one statement concurrently.
2. Can not turn off autocommit if more than database handle is created in the same program.
 
Do these restriction exist if we write our own C programs with freetds, or it is only in perl dbd
with freetds.
 
The version I am using is Freetds v 0.82.
 
thanks
