Yep, I've tracked it down to the meta-programming rather than the 
preprocessing though.

Slow, but OK.

Well at least it gets there in the end :-)

No it's EDG version 3.06.  Strange.  When I get a chance I'll try the latest 
Intel-10 compiler (EDG 3.08) and see how that copes.  Either way, I think I 
now have a workaround that doesn't use Boost.Parameter at all, and will 
*hopefully* be faster to build with all compilers!

Thanks for trying this out, John.
