Perhaps the following snippet from the gentoo ebuild helps:

# GHC build system knows to build unregisterised on alpha and hppa, # but we have to tell it to build unregisterised on some other arches if use ppc64 || use sparc; then echo "GhcUnregisterised=YES" >> mk/build.mk echo "GhcWithNativeCodeGen=NO" >> mk/build.mk echo "GhcWithInterpreter=NO" >> mk/build.mk echo "SplitObjs=NO" >> mk/build.mk echo "GhcRTSWays := debug" >> mk/build.mk echo "GhcNotThreaded=YES" >> mk/build.mk fi

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 Compat/Directory.hs -o Compat/Directory.o -ohi Compat/Director y.hi Warning: retaining unknown function `.L.__stginit_CompatziDirectory' in output from C compiler Warning: retaining unknown function `.L.__stginit_CompatziDirectory_' in output from C compiler Warning: retaining unknown function `.L.CompatziDirectory_createDirectoryIfMissing_entry' in output from C compiler Warning: retaining unknown function `.L.s2U5_ret' in output from C compiler Warning: retaining unknown function `.L.s2PU_1_alt' in output from C compiler Warning: retaining unknown function `.L.s2PU_0_alt' in output from C compiler Warning: retaining unknown function `.L.s2U8_1_alt' in output from C compiler Warning: retaining unknown function `.L.s2U8_0_alt' in output from C compiler Warning: retaining unknown function `.L.s2U9_1_alt' in output from C compiler Warning: retaining unknown function `.L.s2U9_0_alt' in output from C compiler Warning: retaining unknown function `.L.s2Ua_1_alt' in output from C compiler Warning: retaining unknown function `.L.s2Ua_0_alt' in output from C compiler Warning: retaining unknown function `.L.s2Q0_dflt' in output from C compiler Warning: retaining unknown function `.L.s2PH_entry' in output from C compiler Warning: retaining unknown function `.L.r2Ly_entry' in output from C compiler Warning: retaining unknown function `.L.s2U2_1_alt' in output from C compiler Warning: retaining unknown function `.L.s2U2_0_alt' in output from C compiler Warning: retaining unknown function `.L.s2U3_ret' in output from C compiler : : : But I don't know if they matter or are related to my __DISCARD__ problem.
