This is OK.

Also OK.

Not at all.  In fact it is a good thing.

Hmm, I see what you mean.  Really we need some extra logic in the 
definition of POSTSTAGE1_HOST_EXPORTS so that CXX and CXX_FOR_BUILD are 
only defined if they were created in stage1.  Not being an autogen 
export I am not sure how easy this is to do.

My feeling though is that it is better to have the top level files in 
sync, even if it does mean propagating this bug, as there is a 
workaround (configuring with --enable-stage1-languages=c,c++).
