Please, do *not* apologize.  Even if you'd just repeat other observations, your
observations would serve as a confirmation.  But they're also new AFAICT.

So, your recent observation is that gcc-4.7.4 apparently works here.  Looking
deeper into what construct is used in the self-tests, that started working with
that version would likely help, if someone is so inclined.

Or, maybe it'd be ok to just disable the self-testing code before that version.
 Alternatively, plain raising the base version of the gcc being supported for
gcc *development* to 4.7.4 would probably be acceptable too.  To newcomers:
remember, this is just the cross-gcc case.
