I realized after reporting that Fedora 40 updated my gcc version to
14.0. I built gcc 13.2.0 using the tarball from the GNU FTP server and
it occurs there too. Maybe it doesn't for older versions?

$ env GNULIB_TOOL_IMPL=py gnulib-tool --create-testdir --dir testdir1 fstatat
$ cd testdir1
$ ./configure CC=gcc-13.2
$ make 2>&1 | grep '__STDC_WANT_LIB_EXT1__' | wc -l
354

$ find . -name 'Makefile' | xargs grep '^CFLAGS'
./gllib/Makefile:CFLAGS = -g -O2
./glm4/Makefile:CFLAGS = -g -O2
./gltests/Makefile:CFLAGS = -Wno-error -g -O2
./Makefile:CFLAGS = -g -O2

$ find . -name 'Makefile' | xargs grep '^CPPFLAGS'
./gllib/Makefile:CPPFLAGS = 
./glm4/Makefile:CPPFLAGS = 
./gltests/Makefile:CPPFLAGS = 
./Makefile:CPPFLAGS = 

Here is an example of the invocation that shows the warning:

gcc-13.2 -DHAVE_CONFIG_H -DEXEEXT=\"\" -I.  -DGNULIB_STRICT_CHECKING=1 -I. -I. 
-I.. -I./.. -I../gllib -I./../gllib   -Wno-error -g -O2 -MT test-sys_types.o 
-MD -MP -MF .deps/test-sys_types.Tpo -c -o test-sys_types.o test-sys_types.c
