Yes, that's what I always end up doing.  But it would be nice to be
able someday to get my local compiler to rebuild itself :-(.

But even that is not working for me.  Reinstalling a snapshot from
2008-6-6 and a fresh cvs checkout, upgrade.sh gives the missing
.M3EXPORTS failure, and do-cm3-core.sh (after realclean) gets bad
version stamps on Compiler.Platform and Compiler.ThisPlatform,
while compiling SocketPosix.m3.

Going to the most recent (at the time) snapshot of 2008-11-12,
do-cm3-core.sh will run without failures, but leaves a compiler
that always gets the undefined ROOT failure, even trying to compile
a trivial program.

That's right.  The only reason I messed with the cross scripts was that
I hoped they might take care of the necessary bootstrapping in a way
the would work.
