did you notice that it always fills the buffer with random bytes in main()? ;)

it is funny, though, that the same CRC value is generated on separate
machine and multiple runs... something must be wrong with the selection of
the random bytes...

there's no much to compiling it... maybe specifying an output name... mine
defaulted to a.out...

one thing i do note is that it feeds the entire buffer to the update_crc
routine in one shot instead of feeding it one byte at the time... that will
make a difference in the results... especially if there's any pre- and/or
post- processing and where it is being performed...
