@8 is name mangling, used by the (Windows-specific) calling convention
for these symbols.  Probably, a convention declaration was omitted in
ALUT, and not noticed because it would only affect windows.  Report a
bug (http://hackage.haskell.org/trac/ghc/newticket?type=bug).
Disclaimer: I haven't used windows in four years.
