Can't build nofib

[Simon Peyton Jones]

Thanks.  That is very unfortunate: ./configure does not issue any complaint.

I upgraded from 9.2 because GHC won't compile with 9.2 any more.  But now
you are saying that nofib won't build with 9.6?  So that leaves 9.4 only.

Well I can install 9.4 and rebuild everything.  But really, it would be
good if configure complained if you are using a boot compiler that won't
work.  That's what configure is for!
