Hm, yes that may do the trick, for 2.14. Getting the HEAD to compile
with ghc-8.8 is a different matter, but that doesn't need to bother you.

Ganesh: could you take a look at this and perhaps make a new release
2.14.3? There is also a pending patch somewhere against the 2.14 branch
that I made to avoid a problem with Setup.hs.
