Try ++cppf instead of ++ccf.

The compile is failing in the step of pre-processing code to cooperate
with the 3m GC, which is a separate step from invoking the compiler.

I see, though, that if you were building for CGC, then you'd have to
use ++ccf instead of ++cppf, because there's no separate pre-processing
step in CGC compilation. To fix that inconsistency, I think all the
++cppf flags should be used for ++ccf, too, which would be analogous to
the way that CPPFLAGS and CFLAGS usually work (I think).
