More windows woe

[Edward Z. Yang]

I got my hands on a Windows build box, so I'll also go and see if
I can get a build working on Windows.

Excerpts from Simon Peyton-Jones's message of Tue Sep 03 07:33:32 -0700 2013:
> Simon Marlow: please help!
> At the moment windows builds are hosed, which is a Bad Situation.
> 
> Actually it turns out that what want is
> 
>   debugBelch("Checking whether to unload %S\n", oc->fileName));
> 
> That is, use "%S" rather than "%s" as format specifier for wide chars.
> 
> Sadly, this works on Windows, but not on Linux:
> rts/CheckUnload.c:260:13:
>      error: format ‘%S’ expects argument of type ‘wchar_t *’, but argument 2 has type ‘pathchar *’ [-Werror=format]
> 
> 
> So what I need guidance on, please!, is what the approved way to deal with this is.  I suppose that I could identify each use of %s on a filepath and say
> 
> #ifdef mingw32_HOST_OS
>   debugBelch("Checking whether to unload %S\n", oc->fileName));
> #else
>   debugBelch("Checking whether to unload %s\n", oc->fileName));
> #endif
> 
> But that seems deeply unsatisfactory doesn't it?

> If not that, then what?
