BEAM on Win32 is almost a reality today, but has not been thouroughly
tested yet. We are in the process
of distributing a win32 BEAM very soon. 

If you want to compile BEAM on Win32, you will most definetly need to
compile it with a mixture of VC and GCC, due to a few 'missing' features
in VC that GCC has (jump-tables etc). 

I cannot give you more info right now, as I don't have all the details
myself. Anyway, it's most definetly
possible to compile BEAM on Windows if you're prepared to dig a bit..
