I would expect the arguments -Wall -fno-warn-unused-do-bind to be passed to ghc-6.12.1. However, let's see what happens:
ghc [..] -fno-warn-unused-do-bind -Wall Foo
Indeed, that's clearly wrong. The order should be the same as given in the .cabal file.
Any ideas? Why does this happen? How hard would it be to fix?
Where it gets reversed will need a little investigation. First point to check would be before and after finalisePackageDescription.
And are there any workarounds in the meantime?
Have you tried listing the fields in the other order?
Also, I'm happy to file a ticket on the bug tracker for this.
Thanks. Duncan
