Hi,

Just to double check: that means, today it's not possible to generate 64 
bit operations under Windows, including bit level .&., .|. a.s.o. (from 
Data.Bits), and this situation will stay like this for a while.

I'm asking this because I'm currently writing a pure Haskell chess 
engine based on bitboards. The bitboards are 64 bit wide and the basic 
operations are critical for speed, which is always critical in chess 
engines.

Then it looks I'll have to implement these operations in C and use FFI 
to link them.
