I/O activity on the same machine could be the reason of this increase of
the sys time... (I'm not the only one to use this machine)
Maybe I have to run more than once 'time make bootstrap' for having an
average value. 3 seems to be a good value. Another solution is to run
the 'time make bootstrap' on 2 different machines...

I will do.
I have tried to bootstrap a version of 2002-10-05 and 2002-10-06,
but the bootstrap stopped on an error trying to build
I've bootstrapped again the 2002-10-03 on the same machine,
then I'll bootstrap again 2002-10-03 + Roger's patch,
and finally I'll bootstrap 2002-10-03 + Roger's patch + your patch.
I try to bootstrap the 2002-10-07 on another machine, results will come shortly.
