I also see no reasonable way for it to end up as 1. If I printf("%lu") those
same two variables the results are even more strange:
== GCC 4.8.5 ==
GMP_HLIMB_BIT=4294967296=1

GMP-Bugs,
I am trying to build GMP 6.1.2 for ARMv8-A Thunderx2t99 (AARCH64) CPU on
RHEL7.4.
I can build BINUTILS 2.29.1, GMP 6.1.2, and CC 7.2.0 using the system GCC
4.8.5. No errors, GMP passes its `make check` tests. The gen-fac program
works.
Next I use my GCC 7.2.0 to build everything
