Alex and happy use CPP to generate some internal template files, but the code
is unprepared for the output from CPP 4.8.0, which generates LINE pragmas that
contain more information than they thought it would.
By now, it happened twice that a commit broke GHC and thus all Haskell packages
we have in Nixpkgs. On such an occasion, I receive well in excess of 3000
notification e-mails from Hydra, and then I receive another 3000 e-mails after
the bug has been fixed. Under these circumstances, subscribing to these
notifications makes no sense for me.
