I agree with not adding a dependency (although FWIW, bigint does seem
to be there in my minimal perl setups). But can't we fix it like this:

- elsif ($in < 0x100000000)
+ elsif ($in <= 0xffffffff)

At least in a quick test here, "-cw" doesn't moan about 0xffffffff.

For consistency, the other arms of the "if" should be adjusted
