Unfortunately even with that fix I still have trouble building Emacs.
That is, with this recipe:
mkdir d
cd d
git clone https://git.savannah.gnu.org/git/emacs.git
cd emacs
admin/merge-gnulib
./autogen.sh
./configure
make
(same recipe as before, but now with "configure; make" at the end) the
build now fails this way:
CC strtoimax.o
strtoimax.c:44:15: error: redundant redeclaration of ‘strtoll’
[-Werror=redundant-decls]
44 | long long int strtoll (char const *, char **, int);

In file included from ./stdlib.h:36,

The above diagnostic comes because src/config.h contains the line
"#define HAVE_DECL_STRTOLL 0" which is incorrect for this platform. And
that incorrect line comes because ac_compile_for_check_decl is used
before it is set. And this occurs because Emacs's configure.ac's first
use of AC_CHECK_DECL is executed only on alpha platforms (which my
platform is not), which means the initialization of
ac_compile_for_check_decl is skipped.
