All,
I've been toying with the SSE code generation in GHC 7.7 and Geoffrey
Mainland's work to integrate this into the 'vector' library in order to
generate SIMD code from high-level Haskell code.
While working with this, I wrote some simple

Is there a ticket for this bug?
No, but the bug is in the testcase, not in GHC. Is it worth
Oh, I thought the bug was that we don't know how to set a non-Unicode locale on
Windows. Maybe it's not possible (ie bug in windows).
Anyway, I don't mind!
Regardless, worth commenting the expect-broken to say why. Maybe you already
have. I'll go away now :-)
