Hi,

  Thanks for doing more research.  What you discovered made finding a
fix easy.  Thanks.  For semantic 2.0 (in CVS) the following patch may
fix it, though.  I don't have time to try it out right now though.
I don't recall my ... syntax just now, the type of the ... ends up
being a vararg type or some such, yes?

  Apply patch, and press "C-c C-c" in the c.by buffer.

Eric
