Unfortunately this gives rather unhelpful error messages when used
with flags, but it works well enough for now.

Hmmm, I don't seem to get this to work the way I want it.  I get a
"Parse of field 'buildable' failed:" which means configure failed
and then I can't proceed to build the second executable, bar, in
the same package.
Oh, right.  That's a bug in Cabal 1.2 (fixed in HEAD).  Use:
buildable: False
OK, that solved that problem, now onto the next.  Rather surprisingly to
me, buildability has an impact on what's included in the source tar-ball
created with "sdist".  What's the reason for that behaviour?
It seems the source isn't even included on the platform where the
executable *is* buildable.  I'll see if I can put together a small example
and raise a bug.
Done, http://hackage.haskell.org/trac/hackage/ticket/257
