For this error to occur on Slackware, the readline library must be
mislinked, failing to declare a sharedlib dependency on libncurses.
However, although this is a Slackware bug in this particular instance,
there are other platforms where the linker can't find library
interdependency information; for these platforms, FreeTDS would need to
explicitly pass -lncurses on the linker line, /after/ -lreadline, to
ensure that all symbols are correctly resolved.
