I found that I was running into difficulties in using c-macro-expand when the
definition of a macro had more than 1 line.  I looked at the code in
cmacexp.el, and was able to rewrite it so that it behaved itself in the
situation mentioned above.  I'm including a diff made from cmacexp.el as
delivered and my modified version.
