Why don't you try it?  I don't use Windows, so have no hope of doing any
testing (and no incentive to try).

That said, I think there may still be an issue with licensing of the old
AT&T code.  It is said to be 'public domain' and the authors have no
problems with wider dissemination, but you try and get an authoritative
letter out of Lucent Technologies for some code 'owned' by AT&T Bell
Laboratories 10 years ago.....

Further, as Brian Ripley has mentioned, the binary databases are
different for big-endian/little-endian, so for a package to work, you
would have to go back to the data sources or keep two copies of the
databases.  This would make the package even larger, unless you extract
the databases to a separate package or three.  [I use a series of C
programs to convert the database formats between (S-Plus) Unix/Windows
and between (SPARC) S-Plus and (Intel) R.  Until recently I was not
able to create new databases under Linux/Intel.]
