Really? I know that there is a patent concern (Microsoft has patented
one approach to thunks, one that both Per Bothner and I apparently
independently "invented" but a bit different from the one g++ now uses),
but it is work-aroundable.
I think that any claim of a performance concern should be backed up by
benchmarks.

I assume that this would be an ABI for Intel-like hardware? (I can't
imagine an unqualified ABI for all platforms, I think it is too early).
