mapserver binaries for 64-bit windows

[Matthew Perry]

Are there any brave souls out there who have successfully compiled
mapserver binaries for a 64-bit windows server? Are there any
pre-compiled binary packages out there similar to ms4w for a 64-bit
windows platform?

 A quick google search revealed that some people have succeed in
running 32-bit ms4w binaries under a 64bit win2003 server
(http://www.mail-archive.com/mapserver-users@lists.umn.edu/msg00173.html).
Is this recommended?

I'll be deploying under IIS if that makes a difference.

Thanks for the advice,

PS sorry for the cross post to the ms4w list.
