To be fair, they actually fixed a number of similar problems recently,
though I don't know if they happened to fix this one in later versions of gcc.
This specific error seems to be pretty far spread.

Guess you are saying that there is no plan to implement a workaround.
Fair enough; I'll just remove the configuration from my list of tests.

Fixes are in the pipeline for most of the problems. Only exception is alpha;
the patches necessary to fix the problems there only met silence.

I'll probably wait for -rc4 or -rc5 and then send a pull request for everything
that is left directly to Linus.
