Comment (by RyanGlScott):

 I see. In that case, how should `clock` be patched so as to ensure
 backwards compatibility with old versions of GHC? On 32-bit GHC 8.4.2, at
 least, this patch suffices:

 {{{#!diff
 diff --git a/clock.cabal b/clock.cabal

 }}}

 Should that work for other GHCs as well?
