Thanks so much ! It's great.
I will try to report the bug to NVIDIA, but that will be with my words,
I do not have the full understanding of the problem.

Thanks for the bug report. Although nvc 22.1 defines __GNUC__ to be 11
which means it supports GNU C as of GCC 11, that's obviously untrue
for __builtin_add_overflow. That's unfortunate. Perhaps you could
report this as a bug to NVIDIA, as their compiler shouldn't claim to
support GNU C features that it lacks. nvc can set __GNUC__ to be the
version of GNU C that it actually does support.
To work around the bug I installed the attached into Gnulib and this
should appear in the next diffutils release. In the meantime you can
compile with gcc.
