Things worked with exactly only this patch reversed, no other
changes to the system?

Sorry, browsing the patch, I don't see how your analysis could
be correct: you lost me.  Compare the old libstdc++.exp wrapper
with what's in the new wrapper.exp.  Neither does the kind of
target-specific option business that could cause this mismatch:
they're equal except that wrapper.exp saves options, adds -w and
restores options around the wrapper call.  Are you sure it's not
something unrelated to this patch; broken before as well?
