Hello Andrew,

It probably needs to be split into a separate package for distributors (or go
with a libstdc++ library package). As long as it is configurable whether these

is it correct that

S::S::S::S::S()

int main()

compiles? At least other compilers have problems with that.

However, there are some
problems involving ICEs dues to different backend_decls being used for derived

I'm not sure this is related, but note comment #8. Even

From predictive commoning we gain a bit more performance, probably due to the

Any chance of the unrolling taking place while still using PRE?
