For what it's worth: this was also reported to me as Debian maintainer of gmp. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1096730 I've just tested locally, reproduced the configuration failure and have attached the config.log for interested parties. -Steve
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by GNU MP configure 6.3.0, which was
generated by GNU Autoconf 2.72. Invocation command line was
