Not in the short term. We intend to maintain Spirit1 for the foreseeable
future.

The easiest (and best) way is do edit the #include statements in the
respective libraries (I'ld be willing to do that if the library authors
agree) and to define BOOST_SPIRIT_USE_OLD_NAMESPACE to enable full
compatibility with the old code.

I personally wouldn't like to add the possibility to disable the warnings.
We want any depending code to be changed once, and will guarantee
compatibility afterwards.

What libraries are affected, BTW (in addition to serialization)?
