I didn't quite follow all that, but don't you have to restart once
anyway, on Solaris, if the user just does ./configure?  Can't we
figure out before restarting the first time, what should be in
the environment for the second time?  Then we'd need only one restart.

I assume you're trying to avoid the need for _two_ restarts, which
is understandable.

I'd rather not do that; it's pretty slow.
