Greetings,

While building diffutils 3.5 on OpenVMS/IA64 8.4, I discovered:

 I1        5525 #  define _GL_INT_OP_WRAPV_LONGISH(a, b, r, op, overflow) \
 I1        5526     _GL_INT_OP_CALC (a, b, r, op, overflow, unsigned 
long int, \
 I1        5527                      long int, LONG_MIN, LONG_MAX))


This was tripped because the VMS limits.h file does not define LLONG_MIN 
and LLONG_MAX.


I am currently working around this issue by adding:

#define LLONG_MAX __INT64_MAX
#define LLONG_MIN __INT64_MIN

To a pre-include header file on the modules, which works for the OpenVMS 
Alpha and IA64 builds.

Regards,
-John

Thanks, I installed into Gnulib the attached patch, which should be equivalent.
