Too many people out there use Spirit.Classic for it to be pulled from Boost
any time soon. 
Even more as Wave is still based on it as well.

That's definitely true.

It's difficult for me to suggest anything as I have no experience with the
IBM compiler. All I have is second hand knowledge from my talks with Michael
Wong and from what I gather the Boost regression tests. I know they are
working on the compiler to improve Boost compatibility, but Spirit was not
on Michaels list of important Boost libraries to support.

If you look at the tests, you'll see that all are failing for this compiler.
