  Thank you very much. My query has garnered some very useful responses. As I mentioned in my reply to Greg, this program doesn't have to compile on Linux. I'm trying to improve my C programming skills and knowledge. So, this is actually a personal project and exercise in C. As such, getting a solid grip on a cross-platform makefile solution is certainly a great exercise!
