The configuration with mini-gmp, when GMP is not installed, doesn't
compile cleanly. First, compilation in lib/ emits this warning:
CC mini-gmp-gnulib.o
mini-gmp-gnulib.c:28:10: warning: unknown option after ‘#pragma GCC diagnostic’ kind [-Wpragmas]
# pragma GCC diagnostic ignored "-Wsuggest-attribute=malloc"
Next, compilation in src/ yields further warnings:
data.c: In function ‘bignum_arith_driver’:
data.c:2811:9: warning: assignment from incompatible pointer type [enabled by default]

Is this with
./configure --without-libgmp
? If so, I'm not able to reproduce the bug on Debian bullseye. But I
see that mini-gmp-gnulib.c was updated a couple of weeks after you
reported this. Are you still seeing these warnings on your system?

No, this is on a system without GMP. config.log says:
configure:18948: checking gmp.h usability
configure:18948: gcc -std=gnu11 -c -O0 -g3 conftest.c >&5
configure:18948: $? = 0
configure:18948: result: yes
configure:18948: checking gmp.h presence
configure:18948: gcc -std=gnu11 -E conftest.c

configure:18948: result: yes
configure:18948: checking for gmp.h
configure:18948: result: yes
configure:18954: checking for library containing __gmpz_roinit_n
configure:18985: gcc -std=gnu11 -o conftest -O0 -g3 conftest.c -lX11 >&5

configure:18985: $? = 1
...
configure:19002: result: no
The results should be identical, though, AFAIU.

With what version of GCC? This could be dependent on the compiler
version; mine in that case is
gcc (Ubuntu 4.8.4-2ubuntu1~14.04.4) 4.8.4
as was reported originally. (This is on fencepost.gnu.org, btw.)

The warning in mini-gmp-gnulib.c is indeed gone, but GMP-related
warnings in our own sources still remain. Examples:

Does "configure --without-libgmp" help ?

No, I said it _should_ produce the same results.
But I think the other factor here is GCC.

Sorry, I misunderstood you. My gcc version is:
larsi@xo:~/src/emacs/native-compile$ gcc --version
gcc (Debian 10.2.0-13) 10.2.0

Yes. The one which gave me trouble was 4.8...
