Correct.  cppflags are passed to cpp.  ccflags are passed to cc.
Generally, cppflags is a subset of ccflags.   Options that are either
useless for the preprocessor (like -Olimit 2900) or perhaps even fatal
errors for the preprocessor (such as Solaris' -fast) are filtered out.

I don't know specifically what's up with Mac OS X, but the solution is 
definitely not to pass in cppflags to cc.
