(In reply to comment #7)
 Retested on powerpc-apple-darwin and committed.

Since this is a regression, this should stay open until the patch has been
committed in the release branches.  I will backport the fix to 4.0.3 and 4.1.0
for you.

I am going to test this on x86_64-linux-gnu except using gen_int_mode instead
of GEN_INT (trunc_int_for_mode.
