Thanks for your help, but I don't understand what to do. The 
"treedraw"-source is not mine, I found it somewhere. It was created in the 
80's for the windows platform. I never worked with gcc. You can recommend a 
good documentation for an absolute newbie on C and gcc? To be honest, I don't 
have the time to study C and gcc, just from time to time I need to compile 
some source, which normally works fine.

Yes, it is on Debian 3.0.

Thanks for your patience
