Does libstdc++ v3 not work with Canadian crosses?

Not recently, but yes. The experience is quite hard to forget, as I 
suspect you are finding now.

Completely aside to this: the problems with mknumeric-limits and cross 
hosts, multilibs, etc get resolved if Scott Webb's staging header patch 
goes in. This moves much of the generated header bits from being a 
configuration-time issue to a build-time issue.

I've actually got that patch merged in. I'll post the diffs later today.
