Pretty sure that should be "int main (void) { return 0; } ".
Surely that is not how the implicit main() declaration looks? A new
compiler warning is warranted. So add (int argc, const char **argv)!
Oops, unused parameters, darn. We need to make a fake dependency on
these unused parameters...
Alternatively, we could develop GMP.
How hard can it be to patch that in the configure.ac autotools stuff?
It is pointless to work around compiler idiosyncrasies without a plan,
and without clear indications that it solves a real problem.
These should be fixed upstream in Autoconf already:
https://git.savannah.gnu.org/cgit/autoconf.git/commit/?id=8b5e2016c7ed2d
This is a somewhat well known change in Clang (and upcoming, though not
current, GCC), and is also a change that was done in ISO C over twenty
years ago.
We, as well as Fedora, and likely others have been fixing these in
various programs for a while:

Dennis, would you mind testing with Autoconf 2.72c to see if the issue
persists? You can fetch it from
https://alpha.gnu.org/gnu/autoconf/autoconf-2.72c.tar.xz
This is not entirely off-topic for GMP/MPFR but certainly out on the
bitter edge. Maybe best to move this off to a maillist for autotools.
Thus, I will get onto that for a few systems. Likely :
1) FreeBSD 14.0 ALPHA2 on the RISC-V rv64imafdc
2) FreeBSD 14.0 ALPHA2 on aarch64
3) Gentoo Linux on sparcv9
4) other stuff running around me ... :)
