	You can generate approximate solutions by using FindRoot instead
of Solve, but if you want complex solutions you have to indicate that.
For example:

Subject: [mg37426] [mg37422] Approximation of complex solutions

I would like to have mathematica attempt to find complex solutions to

cos(cos(cos(cos x))) = sin(sin(sin(sin x)))

It always tells me the variables appear to be related in a non-algebraic
way.  Is there a way to have it approximate these solutions?
