"invalid token pasting" macro bug

When I use Spirit with CodeWarrior 9 (just released), I get a bunch of 
warnings as shown below.  The CodeWarrior release notes explain that 
"According to the language standard, the '##' token pasting operator 
can only generate other tokens.  This warning indicates when a paste 
was found that did not result in a token.  The code will still compile 
as it did previously, but it may be a useful hint if the compiler emits 
an error later on."

Warning : invalid token pasting of 'BOOST_PP_LIST_FIRST_I' and '('
(included from:
  expanding macro 'BOOST_PP_LIST_FIRST'

  expanding macro 'BOOST_PP_FOR_1_C'
