I've never seen those error messages.

You could run cmoc with the --verbose option to see how cmoc calls the
C preprocessor. That would allow you to check if it's the cpp command
that generates those errors.

The output of that cpp command may present lines that cmoc doesn't
expect. Lines that start with '#' are expected to be of these forms:

    # 1 "foo.c"
    # 1 "foo.c" 42

On my system, I'm using cpp 4.8.4.
