That suggests that the file has been compiled with the wrong GCC options
compared with the rest of the code, e.g. perhaps without -mno-cygwin.

You can see from the comment at the top of the file that this file is just
prettying up the default error output of GHC's RTS, so it's not needed, but
equally needn't be removed.

I think the problem is that the file is getting compiled directly with gcc,
and doesn't therefore have __GLASGOW_HASKELL__ defined. __GLASGOW_HASKELL__
is definitely 501 with the latest InstallShield compiler.
