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.
OK, I might take a look.
And are there any workarounds in the meantime?
Have you tried listing the fields in the other order?
Yes, with the same result. So it's not as simple as something being backwards. I just had another idea for a possible workaround (even if this gets fixed I'd rather not rely on everyone building xmonad to have a sufficiently new version of cabal) which I will try once I get to school.
Also, I'm happy to file a ticket on the bug tracker for this.
Thanks.
Will do, I mailed first to see if people agreed this was a bug. -Brent
