Hi, for some reason hsc2hs does not fail if the automatically generated program fails to execute. This only happends if I forget to set LD_LIBRARY_PATH before saying make. But it leads to a confusing error messages when an empty .hs file is left and ghc complaints with "file name does not match module name". The patch below was done against ghc-5.02.2 on FreeBSD.
