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.
