I worked a little more on Semantic byte-compilation issues when both
the speedbar and eieio are not installed.

In that case to safely byte-compile the core of Semantic I had
to remove all the `require' statements inside `eval-when-compile'
forms.  The counterpart is a lot of warnings :-(

The files that can't be compiled are: semantic-analyze.el,
semantic-cb.el, semantic-chart.el, semanticdb.el, semantic-ia.el,
semantic-ia-sb.el.  Because their code directly depends on eieio
(defclass, defmethod, etc.).

So there is two solutions possible:

  - Always install semantic, eieio and speedbar together (I would
    recommend it).

  - Remove the requirements at compile time (and ignore the bunch of
    compilation warnings).  Of course the libraries that depend on
    eieio will fail to compile if eieio is not installed!  And the
    semanticdb and chart stuff will not be available!

Providing a "cedet" package with its own version number (and
Project.ede and Makefile), including compatible and up-to-date
versions of eieio, semantic and speedbar could be a good solution.  It
will simplify installation and other packages like JDEE or ECB could
just depend on a "cedet" level.
