Dear Ingo and Markus,

thanks for the beta.  In order to be able to use it we had to make
the corrections you will find in the attached patch.  They fall into
5 categories:

1) namespace errors whereby some std:: qualifications were missing;
2) namespace errors when compiling (as we have to) with FILIB_NAMESPACES
    defined;
3) incorrect uses of abs() (an int -> int function) instead of fabs()
    (double -> double);
4) undefined type `Complex';
5) unused variables (causing annoying warnings).

We are now using the revised beta version.  However, we could not disable
our wrapper around the pow() function, since CoStLy still throws an exception
for invocations like, e.g., pow(([-0.5, -0.5],[0, 0]), ([-1, -1],[0, 0])).
Do you plan to address also this case?
Thanks a lot

      Roberto
