Off hand I don't know what the "-mno-486" flag does but by ANSI C 
definitions, an signed integer as you have declared "i" to be; has the 
maximum and minimum values of -32,767 to 32,767. You want to declare "i" 
as a unsigned int ( now i can be from 0 to 65000 ) or a unsinged long or 
long int which gives you 4 million for the unsigned long or +/- 2million 
for the signed long int. 

Hope this helps,
Don ;)
