[Haskell-cafe] What to do when GHC works, RUNGHC fails

This seems to be the same bug:
  http://hackage.haskell.org/trac/ghc/ticket/1883

The ghci linker is a custom one (AFAIK) and is "different" from GNU
ld. That's a feature, not a bug :-) GNU ld, for example, can find
either of libxxx.dll or xxx.dll if you say -lxxx.

See this ticket for another difference between ghci and GNU ld (ghci's
linker tries to link _all_ symbols in the library archive, rather than
just the modules that you're using):
