You should use command like this:
D:\djgpp\practice>gxx -I..\djgpp\rsxntdj\include -o test.exe test0022.cc

I think you should try to include only one version of "types.h"....You can use
"#ifdef" for not including it twice...
but anyway you can try using "namespaces". As far as I remember it allows you to
use functions with the same names included from different sources, when you need
functionality of both of them....
Someone correct me if I'm wrong...
