| # Make sure we support the latest prerelease GHC. This means validating that Cabal doesn't | |
| # output a warning that the GHC is too new. | |
| # | |
| # It's generally pointless to run this when not around a release, but there's no good way | |
| # to automate checking for that so we just run pointlessly. (If it doesn't succeed, we have | |
| # bigger problems.) | |
