I just redid the experiment with 7.0.3 vs. 7.0.2, and now only the hash
of the ghc package changed when building 7.0.3 with 7.0.3 instead of
7.0.2, but the other hashes stayed stable. Given that only few libraries
use the ghc package, this is good enough for Debian.
I’m uploading ghc-7.0.3 to Debian very shortly, but will not rebuild it
before triggering rebuilds of all libraries.
