switching from 32 to 64 bit *integers* caused it, so if the compiler chose 
to implement it using floats, well, i blame the compiler. but given the 
existance of do_div() i assume whoever knew this and thus provided a 
portable mechanism for doing division in the face of being (most likely) 
unable to provide true 64 bit ints on all platforms.

so why can't i divide them? ;-)
