Right. But the 2.x system should build the compiler (and bootstrap libs)
statically and install them in /usr/obj/..../tmp. Then the "make world"
should stop dead in its tracks and use the compiler in /usr/obj/..../tmp
[which itself is an a.out binary] to start a new "make world" where the
output are ELF images. I've glossed over a little bit here -- I think
maybe we need a /usr/src/Makefile.aout-to-elf and the upgrade path is
now:
make -f Makefile.aout-to-elf {,buildworld,installworld}

True.. and I bumped into the same mess in the compiler upgrade

As I did in the EGCS bootstrap. ;-)
