This is getting confusing.  I'm asking you at this point to read the
chapter "Config Basics" of the CC Mode manual.  About 36 lines down from
the top, it explains how setq'ing/customizing CC Mode's style variables
interacts with loading a buffer.

I don't think this is a bug.  When you've read that manual page, would
you please check exactly what you've done, and whether your buffer
indents as we both would like.

If it still seems wrong, could you give the exact description of how to
create the problem starting from emacs -Q (yes, I know this'll involve
some repetition).

Thanks!
