What are your CPPFLAGS and CFLAGS?
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 Collin
