Gnulib now assumes that the C compiler supports 'long long' [1].
VMS on Vax is end-of-life for more than 7 years now [2], and the
other CPUs on which VMS is running (alpha, ia64, x86_64)[2] are all
64-bit.

I would say that it's not worth the effort - except for the person(s)
who care a lot about Vax/VMS.
