I'm afraid 2.6 ain't gonna do it.  sizeof (void *) == 4.  Sun's
official position on 64-bits is "gradual transition", not DEC's cold
turkey approach.  About the only 64-bit thing you'll be able to do in
2.6 is file I/O.  But Sun is working on it.

Of course, we can expect all major OS'es to gradually adopt 64-bit
models.  The 32-bit and 64-bit models will co-exist for a long time.
It will likely be 2020 before the XEmacs sources can abandon 32-bit
support.
