[Haskell-cafe] Porting setlocale to Windows

[Sven Bartscher]

I assume that "do nothing", means that a call to 
`setLocale LC_MESSAGES x` always returns Nothing (which may confuse
some applications, but maybe it does in the right way).

Then there's the question left, what categoryToCInt does. I could
change it's signature to `Category -> Maybe CInt`, but that would mean
breaking the API. Instead I could make say 
`categoryToCInt LC_MESSAGES = -1`, which may confuse some applications
which assume that categoryToCInt returns valid integers. But I guess,
that's not that much of a problem, since categoryToCInt is not really
often used in packages other than setlocale itself.

Sven
