fix_c.r called at ese2rdae stage so that pow gets fixed in ae.r.

These changes produce the desired result (optimised algebraic equations) but
have highlighted a problem; when optimisation fails, Reduce does not write
a result. For complicated systems, this can lead to missing assignments in
the resultant code. check-in: ea9834becc user: geraint@users.sourceforge.net tags: origin/optimise-algebraic-equations, trunk
