I have prepared the pull requests necessary to encode the address-model (32 
or 64) in the library names, which allows placing the 32/64 libraries into 
the same stage/install directory, and building with address-model=32,64 in 
one go.

These are

and

This being a Serious Change, the prudent thing to do is to wait out 1.65, 
then proceed.

On the other hand, experience shows that this kind of change is only tested 
when a release goes out anyway; delaying it for four more months would not 
help much.

Therefore, I'm calling for opinions; would people want this to go into 1.65? 
Into 1.66? Not at all?
