-# Unregisterised HC packages are architecture dependent. We have to
-# create more HC packages to support more architectures. Note that
-# these packages are built with integer-simple, not integer-gmp, to
-# reduce some complexity by not depending on the GMP. The resulting
-# registerised GHC uses integer-gmp so this won't be a problem.
