We still haven't since I'm now not able to replicate the problem...

My best guess is that I had Cabal old installed, which didn't support
--builddir. I upgraded to Cabal new which did. Cabal install had
cached the Setup.exe program built before the upgrade so that the
Setup.exe still used Cabal old. Now, when I try again today, it picks
up Cabal new.

I guess there is a potential bug that cabal install should perhaps
rebuild setup.exe if the cabal version has changed, but that might be
difficult to track and is very much a corner case.

Fantastic. If I break everyones build, I'm blaming you :-)
