I was thinking that keeping the C host compiler would make the switch
possible during this stage3 (there were only very recent reports of fails
to use other than GCC host C++ compilers).  It basically decouples the
host compiler issue from all the rest.  And it would make sure that for
the next few month a bootstrap with C++ is actually possible, so patches
for 4.7 could be developed with the possible use of C++ in mind.
