No joy. Trunk as of a few hours ago, r164755, still fails with the same
bootstrap comparison failure I showed earlier. I did run into PR45837 but
Meissner's patch cured it.

Thanks for the testcase.

seems to help with the testcase. Does it also fix bootstrap?

Yes it unbreaks bootstrap.

Is there a problem with Alexandre Oliva's PR42289 patch that's causing it not
to get applied? I still (3+ weeks) have to apply it to get past the bootstrap
comparison failure with trunk on ppc64-linux.

Bootstrap works again in 4.6 r166408, presumably because r164552 was reverted.
