Perhaps You used project files from RHIDE-1.4.6 source distribution archive. Then all 
sources from libtv.a is built with compiler options '-fno-rtti -fno-exceptions'. So to use 
TVision in Your applications either rebuild libtv.a without these options or
use same options for Your sources. I think Robert turned off
exceptions and RTTI to have smaller executables, as these features
is not used in RHIDE. 

Perhaps it may be sufficient to remove -fno-rtti from gcc options
when building libtv.a

Try:
  
gxx -fno-rtti -o listbox.exe listbox.cc -L/djgpp/contrib/rhide-1.46/tvision -ltv
