I got many warnings when compiling Gnus.  For instance:

smime.el:123:1:Warning: defgroup for `smime' fails to specify containing group

I think there might be customization groups which don't belong
to any parent groups except `emacs'.  Although it is possible to
avoid warnings by adding the ``:group 'emacs'' parameters, I
don't think it is useful especially for `defgroup'.
