In my experience, yes.  But I have really only taken .exe's compiled on XP to 
run on Vista and w2k3.

I don't think you'll have any success in running a 64-bit executable on a 32 
bit system.

However, I think most 64-bit systems are able to run 32-bit executables.  I 
suspect GHC, with its static linking is a rather easier platform than C/C++ 
with its typically large set of shared objects.
