I don't really claim to understand how the old code was going to achieve
that with that check.

But I did make an alpha cross compiler, and a cross mig for alpha-gnu, and
verified that my change doesn't change anything for alpha.  I didn't expect
it to change anything, because we don't have 128 bit types :)

So, because my change seems to be an improvement over the old code, the old
code never worked on 32-bit machines with 64-bit parameters, and we need a
new version of mig for our users and the Debian archive, I checked in my
fix.  Feel free to improve on that if I did something stupid or did not go
all the way.
