Hello Dan,
thank you very much for your interest.
I will work again on the $csign funtion which will give correct answers for
complex expressions. Most of the work is done. But it is some time ago I have
written the code.
In addition I have implemented generalizations for the functions abs, arg,
signum, ... which give a better support for complex expressions too.
But first, I would like to finish some work on the integration routines of
Maxima.

I think this sounds extremely valuable - please go ahead and commit.
