As of gnulib commit 4a127339b244 coreutils CI is failing on GCC 10 with:
CC src/coreutils-coreutils.o cc1: error: command-line option '-Wuseless-cast' is valid for C++/ObjC++ but not for C [-Werror] cc1: all warnings being treated as errors I know it's old and it's -Werror so developer specific, but perhaps it could be easily avoided. cheers, Padraig
