After the autoconf update to 2.73 this was using -std=gnu23 even on hosts with gcc-13 which doesn't support it: ac_cv_prog_ac_ct_CC_FOR_BUILD='gcc ' ac_cv_prog_cc_c23=-std=gnu23 ac_cv_prog_cc_g=yes ac_cv_prog_cc_stdc=-std=gnu23 Leading to: gcc -std=gnu23 -DHAVE_CONFIG_H -I. -I../../sources/audit-4.1.4/lib -I.. -I. -I../../sources/audit-4.1.4 -I../../sources/audit-4.1.4/auparse -I../../sources/audit-4.1.4/common -isystem/audit/4.1.4/recipe-sysroot-native/usr/include '-DTABLE_H="fieldtab.h"' -isystem/audit/4.1.4/recipe-sysroot-native/usr/include -O2 -pipe -c -o gen_fieldtabs_h-gen_tables.o `test -f 'gen_tables.c' || echo '../../sources/audit-4.1.4/lib/'`gen_tables.c gcc: error: unrecognized command-line option �-std=gnu23�; did you mean �-std=gnu2x�?

Reviewed the changes. The PR updates m4/ax_prog_cc_for_build.m4 from serial 8 to serial 26 and is a byte-for-byte match with the current upstream at https://gitweb.git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_prog_cc_for_build.m4

I was waiting for autoconf-2.73 to show up in rawhide. Build checks good. Thanks for the patch. |
