https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107116 This bug was in GCC 5 and is still present in GCC 12.To work around the GCC bug, please use './configure --disable-gcc-warnings' instead of plain './configure'. Or (and this may be simpler) please use the latest coreutils release from <https://ftp.gnu.org/gnu/coreutils/> rather than trying to bootstrap. Another possibility is to upgrade to GCC 7 (2017) or later, as these GCC versions have __builtin_sub_overflow which means the code in question will not be compiled.
I doubt whether we should modify Gnulib or coreutils to work around the GCC bug, as we expect developers who are bootstrapping to use up-to-date tools and GCC 6 is not up-to-date. I'm therefore closing the coreutils bug report.
