Can't we fix such a _hypothetical_ crash when someone finally reports it?
In fact I bet we aren't going to be able to prevent folks from running
on NT4 anyway so we will have to fix it.

If the installer can't run on NT4 SP4, that is an installer issue. I
don't see why we should label the base source code as not working on it.
If it doesn't have symlinks, fine, no tablespaces. I will update the
release notes to mention the installer doesn't run on NT4.

Basically, we can't turn the PostgreSQL ship on a dime. If we come out
and say NT4 doesn't work, the someone else appears and gets it working,
it is harder to communicate that. I don't want to be adding/removing
NT4 based on untested ideas.
