I'm not sure there's any real problem here. If you do C-c C-s on a
line with a macro, don't you get cpp-macro along with some other
symbols? If you do, everything is as it should be, and you ought to be
able to configure the indentation you want.

c-set-offset might not default to cpp-macro, but that doesn't mean it
doesn't exist; it's just that c-set-offset defaults to the last of
several symbols that matches the line (i.e. in the list that C-c C-s
gives).

I'm not aware of any function with that name, but I guess you mean
c-comment-indent. It doesn't use the syntactic analysis to recognize
macros, but it does assume that all macros have a '#' in column zero.
I've relaxed that now (and also some other places that assumed that
the same thing). This was afaik not a newly introduced bug, however.
