It would be good if the packages that need base 4 say so. If the 
package repos are shared with anyone else, it would be good if
the packages worked with either base 3 or base 4.

Ok, by unpulling the partial base 4 support patches for several
packages, and specifying base < 4 for all extralib packages, I was
able to build a full head (minus the packages that have been dropped
recently). And 'make binary-dist' completes as well, yay!-)

I didn't see an installer, but then I don't miss that at the moment.
However, unpacking the tarball reveals some gaps (haven't checked
yet whether anything else is missing):

- no runhaskell (runghc is there, though)
- no ghc package (neither hidden nor otherwise; it is present
    and hidden in the inplace ghc)

Anyway, progress, or at least: visible results of same!-)

Thanks,
Claus
