    AMD hudson: Round the float pointing number to integer
    
    Try
    sh> printf %d 0x005500AA | LC_ALL=C awk '{printf("%c%c%c%c", \
        $1 % 256, $1/256 % 256, $1/65536 % 256, $1/16777216);}' | \
        od -Ax -t x
    On Linux with gawk, we get
       000000 005500aa
       000004
    On FreeBSD with nongnu-awk, we get
       000000 000055aa
       000002
    
    In awk, all the numbers are floating point number. So division doesn't
    round the result from 0.75 (3/4) to 0.
    And, There is a fact that, for the FreeBSD awk,
    sh> awk 'BEGIN {printf("%c", 0.75)}';
    produces nothing, instead of 0.
    
    Here we need to convert the floating point number to
    integer by int(X), which is an awk built-in function, instead of GNU
    extension.
