Amazing!  Thank you for your efforts.

Please show the definition of 'struct rlimit' on your system.  It
should be in the header sys/resource.h, I think.  Then perhaps I will
have some insight.

Reverting the change is out of the question, sorry.  The 'long' data
type used there before the change is too narrow to support some of the
systems which use this code.  We will have to find another solution,
if indeed this is the problem.  But first we need to understand the
problem.

Thanks.
