You should look at what comes before that token and from where,
that might be a reason why the extern "C++" is rejected at that spot.
So, preprocess it (-save-temps or -E -o src/sipp-sipp.ii) and look in the
preprocessed dump. Perhaps cstddef is included in some context where it
shouldn't be or there are macros redefining extern or similar bogosities.
