I'll add that. Phil Moore sent me a patch for the Sybase::CTlib module
quite some time ago for the _r libs (before there were 64 bit libs), and
for some reason I never ported this to the DBD::Sybase code line.
The _r libs are only needed if you are effectively going to do
multi-threaded programing, and accessing DBD::Sybase simultaneously from
multiple threads. Note however that I haven't tested DBD::Sybase for
thread-safeness, so there are no guarantees...
