This positive attitude strongly suggests that you haven't looked at the 
64-bit ABIs yet. Of course, they differ for Windows, Linux, and OSX. 

Once you start using 32bit Windows calls, be prepared that your users 
will not like deep changes when they move from a 32 to a 64 bits OS.

Making a Forth program independent from the cell size is not a big deal
(for 32/64 bit), but it can't be done without extra words that better 
are standardized first. One of the pitfalls is that offsets and sizes
of OS structures are kept 32bit, even on a 64bit OS, except when they 
aren't.
