oh, it is caused by -Werror.

conftest.c:59:1: note: 'atan' is declared in header '<math.h>'
   58 | #include <limits.h>
   59 | #undef atan
cc1: all warnings being treated as errors

See also:

   54 | int64_t x;
      |         ^
cc1: all warnings being treated as errors

Now with

        CFLAGS="-g -Wall -fno-common -Wextra -Wunused" \
     CXXFLAGS="-g -Wall -I/usr/include"  \
            ./configure --prefix=/opt/grass \
            --enable-largefile --enable-shared \
            --with-blas --with-bzlib --with-cairo --with-cxx
--with-freetype \
            --with-freetype-includes=/usr/include/freetype2 --with-gdal \
            --with-geos --with-lapack --with-netcdf --with-nls \
            --with-odbc --with-openmp --with-pdal=no \
            --with-postgres
--with-postgres-includes=/usr/include/postgresql \
            --with-proj-share=/usr/share/proj --with-readline \
            --with-sqlite --with-x --with-zstd

it compiles...
