Yes, this incidently happens with Sybase's OpenClient libs as well, as we
moved from --with-sybase to --with-sybase-ct on our AIX machines when we
had to compile DB2 in as well.

On the other hand, I ran into incompatibilities between dblib and a
realtime graphing package that was not so easily separated. ctlib has a
much more thought out naming.
 
I've got a list of things I need to make patches for on PHP wrt
freetds when I get the time...
