Jezus! (sorry), why do you want to do this on an Archimedes??????
Ok, it is interesting to see the Bresenham algorithm. But since the 
operating system supports lines (and other graphics stuff), why should
you go wild and implement your own line routines in C?
for speed? The OS routines are in Arm code, if you want them to be faster,
rewrite them again in Arm code, not in C.

NO, I DON'T WANT A LANGUAGE DISCUSSION AGAIN!!!

Remember that Risc OS is an Operating System, which supports the programmer,
and not a Disc Filer (like DOS), which hinders the programmer.
