 Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

 make[1]: *** [libraries/ghc-prim/dist-install/build/GHC/Generics.o] Error
 1
 make: *** [all] Error 2

 ---------------------------

 Note: configure failed in the first place, but I followed the hint
 at http://passingcuriosity.com/archives/ on 01 Sep 2009 and
 changed the last line of bin/ghc-6.12.1 into

 extraoptionen="-optc-m32 -opta-m32 -optl-m32"

 exec "$executablename" $extraoptionen -B"$topdir" ${1+"$@"}

 This allows configuration. That blog indicates that, later,
 one might need something like -optl-arch\ i386 in that same
 script. I do not know what to do here. I cannot find any of these
 options in the documentation.

 I keep the whole output of running make in a file (including redirection
 of error output) and can provide it if needed.
