lim_data needs to be at least as wide as the rlimit .rlim_cur field or
truncation occurs.
It would seem that on a 64-bit machine, lim_data should
be a 64-bit type. Is there any agreement on how to
specify such a type in C?
We could use configure to check whether rlim_t is defined
in some header file. What header file should it be in?

Modern compilers should support the int64_t type (it is mandated by
the new C99 standard and should be defined on stdint.h).

According to Posix, it should be in sys/resource.h.

Modern compilers should support the int64_t type (it is mandated by
the new C99 standard and should be defined on stdint.h).
Do we want it to be 64 bits on all machines? I suppose it would
not do any great harm.

According to Posix, it should be in sys/resource.h.
In that case, let's make configure check that rlim_t is really
defined, and use it if it is defined.

Wouldn't something like size_t be preferable?
