Thanks for that tip - I shuold have thought to check.
Unfortunately I still get the same undefined __DISCARD__ with that.

Also perhaps I should mention that earlier I am seeing a *lot* of warnings
like these:

/usr/bin/ghc -H16m -O -I. -Iinclude -Rghc-timing  -ignore-package
Cabal -I../libraries -fglasgow-exts -no-recomp    -c

But I don't know if they matter or are related to my __DISCARD__ problem.
