I'm sure there are still a few people with older hardware.

I re-uploaded the DevC++ compile. I took out the unneeded explicit casts, because like a moron I was compiling the program as C++ and not C. Also, I added the -std=c99 switch to the command line. If this doesn't work for Norbert, I am setting a blowtorch to my computer.
