Curiously you are right. Target is
Weird since it's a 64-bit machine.

If you have a 64bit Windows machine, then you'll be able to run both the 32bit and 64bit GHC builds. If you run "ghc --info | grep Target" then you'll see which is being used - it'll say x86_64-unknown-mingw32 if it's 64bit, and i386-unknown-mingw32 if it's 32bit. I suspect that you have a 32bit GHC, so comparing with the 32bit numbers is right. They probably just need updating for recent wobbles.
