FWIW, I touched on this in the 1/4 message, but (unhelpfully)
not in the one above the patch itself:

The problem is that gcc/ wants to do something slightly different
and the libstdc++ code is bound up with other things. The changes
didn't look entirely mechanical.

In case anyone else is wondering about that, 4/4 only affected
libjava, so I only posted it to libjava-patches. I should have
made that clearer, sorry.
