I'd hate to see cruft added to fusion, however little to resolve this
issue. I see 189 usages of nil in boost 1.44.0 and 202 in 1.47.0
primarily with spirit/xpressive. Both these boost versions compile fine
with our code. I'm trying to understand what might be different with
1.48.0 that causes the conflict to arise. Is there a config file 'not'
being included in 1.48 that was #undef'ing nil?

I'll do a little more investigation.

Thanks, Jeff
