er ... that's why I asked how to do it properly. I simply included the 
diff to show what I had been able to make work, not because I wanted it 
applied.

I'm still trying to find out. But I don't see why this is different from 
the kludge we already have for unlink, and that one is right inside 
postgresql. In fact. it's more or less the same solution.

At the very least, until we can find a better solution we should have 
something like the checking part of what I did. We've seen quite a 
number of obscure failure reports that have all been traced back to this 
failure, which is currently quite unreported by configure.
