The last GHC built with this patch applied was x86_64 ghc-7.9.20140917. 
I had no problems with that build.

I've made only the minor modification today (20141027) to let it apply 
to today's HEAD cleanly.

The last 32-bit build was made 4-6 month ago perhaps.

I have no much time to test this patch agaings today's HEAD, so I would 
greatly appreciate if you consider this as a final version (and report 
the problems if any).

Cheers,
Kyra
