I'll expand my comment here. The idea is that if you -I srcdir, you'll
get in the way runtime sources of the new compiler, and they don't mix
with those of the build compiler. By using the build dir, you get
objects and ALI files of the new compiler, bad too. Hence we need a
clean directory (or may be it can be done with complicated flags, I
found the tmp-dir just simpler).

I'll wait for ACT input on this, and resubmit a patch later today
incorporating your fixes.

Thanks for your comments!
