You are using gcc 2.8.x (2.8.0 perhaps) and this library was compiled with 
2.7.

The last is the better thing. Download:

1) The RHIDE sources (http://www.tu-chemnitz.de/~sho/rho/rhide-beta.html for 
RHIDE 1.4.5).
2) Read the readme files inside the sources, they explain what tools are 
needed to compile (make, fileutils, sed, etc).
3) You don't need to download the gdb sources.
4) Download the  tv.zip TVision sources from *Borland*, the URL is in the 
RHIDE readmes or in my pages.
5) Put the tv.zip file in the directory that RHIDE states in the readmes. 
Don't uncompress it just put the file there.
6) Be sure you have unzip from the InfoZip project in your system (don't 
rename pkunzip, don't use Borland's unzip).
7) run "make tvision/include/tv.h" and cross your fingers ;-))
