Gilles,
thanks again for pointing out my tyo screwup. I fixed that and tried
again, but
still no luck. Below is what happens now. This does not look like an actual
error, just some not so clean coding, hiding a potential error. I also saw a
questionable type cast warning zip by at some point.
For the time being it might be just a matter of treating this as a
warning, not
as an error. Since I have absolutely no insight into the make
infrastructure of
this project and what compiler switches are on or off at any given
point, can
you suggest a course of action?
The updated script is below again for reference.
Elmar
