Yep.  Although I think we currently do the same.  With this reasoning we
also wouldn't need to build the fortran, C++, ObjC and java compilers in
each stage (or generally all frontends written in C), as it's only the C
compiler which is anyway excercised here.  AFAIK we don't do anything with
those compilers in stage2, so we could defer also those to stage3.  Would
throttle back bootstrap times a little.


Ciao,
Michael.
